librenms-agent's Issues

zfs-freebsd: Can't run on FreeNAS

It requires a perl module that doesn't come with FreeNAS, and you can't really alter OS packages on FreeNAS because they get blown away each time you upgrade. What I did is port the script to python and only used the standard library.

Note shebang line specific to system... /usr/bin/env python3 failed on FreeNAS so I haxed it. Needs fixed properly.

snmp mysql script seems to be flawed

1. the script does not provide a simple output variable indicating if the host is a mysql slave at all or not. This would enable the monitoring host to switch slave status data on or off, depending on if there is anything to monitor at all.

2. In lines 414 to 418 it is setting the slave_running and slave_stopped output variables in a way that makes them very hard to use sensibly. For example, if slave_sql_running is not Yes, the value is set to 0. If if is Yes BUT slave delay is zero (which happens to be the case really often), it is ALSO 0. So to determine if your replication needs attention, you would have to check if lag is >0 AND sql_running is == 0.

smart script doesn't handle nvme drives

I have a server with a single NVMe drive and no other SATA or SAS drives. The smart -g option to generate a config does not seem to account for NVMe devices at all. Manually editing smart.config to set device type of NVMe also results in the script outputting no data.

$ cat smart.config
useSN=0
smartctl=/usr/sbin/smartctl
cache=/var/cache/smart
# # scan_smart_devices: glob(3) aborted matching pattern /dev/discs/disc*
nvme0n1 /dev/nvme0n1 -d nvme

PHP extension mysql is deprecated

In Php7 there is only mysqli

add support for icecast2?

Hi,

Is it possible to monitor the amout of listeners from an icecast server?

I have setup this script that pushes the amount of listners via snmp.
https://github.com/mattyribbo/icecast2-snmp

Output from snmpwalk:
`user@librenms:/$ snmpwalk -c secret -v 2c 192.168.3.2 .1.3.6.1.4.1.8000.2.1

iso.3.6.1.4.1.8000.2.1 = Gauge32: 0
`

Also I have tried the shoutcast application but not sure it will work with Icecast or if I have configured it incorrectly?

Recommend removing file librenms-agent/agent-local/bind

This led to me to some confusion following the new BIND/Named application update. Since the agent is actually one and the same as the SNMP extend script now I'm thinking librenms-agent/agent-local/bind is obsolete and should be removed.

librenms-agent/snmp/exim-stats.sh resturns only frozen emails

Hi,

I am trying to use librenms-agent/snmp/exim-stats.sh with Exim app in LibreNMS. It returns only one line containing number of frozen emails. While in fact it should return also queue size:

./includes/polling/applications/exim-stats.inc.php:

[...]
$stats = snmp_get($device, $oid, '-Oqv');

echo ' '.$name;

list ($frozen, $queue) = explode("\n", $stats);
[...]

osupdate script doesn't work on Fedora

It appears that the latest changes to the osupdate script broke the package-manager detection on Fedora and possible other OSes too.
I am not sure, but I think the addition of '/usr/bin/env' in the variables in combination with the usage of '-f' doesn't work. The script always falls back to the last 'echo "0"' statement.
When I update the script to use the full path to the package manager (/usr/bin/dnf in case of Fedora) without adding /usr/bin/env it does work.

multiple apps broken since February 6th including bind and mysql

The bind and mysql application graphs appear to no longer function. A debug poller run shows it is no longer looking for these apps so I suspect it's an issue in the librenms repo. Example:
https://nms.baxterit.net/graphs/to=1488515700/id=7/type=application_mysql_connections/from=1485837300/ demo:demo

zfs-linux attempts to use a switch (-p) not yet ported from freebsd

librenms-agent/snmp/zfs-linux

Line 98 in ae3fded

proc = subprocess.run(['/sbin/zpool', 'list', '-pH'], stdout=subprocess.PIPE, universal_newlines=True)

The -p switch for parseable isn't available in most packages for ZFS on Linux. In fact, it was only committed to the upstream late last year. Presumably this is a hangover from the original FreeBSD version of the command.

This is breaking on all Ubuntu up to and including 19.04.

mysql script doesn't support unix sockets

The mysql script doesn't seem to support connecting to the mysql server over a unix socket. This is important for mysql servers like MariaDB that can authenticate users via unix_socket. This would allow us to run the mysql script on the localhost without embedding a password in the script. Please fix.

OpenWrt not detected

Hi,
LibreNMS keeps detecting all of my OpenWRT/Lede devices as Linux and then kernel version.
Version of OpenWRT or Lede makes no difference as well as kernel version.

I can manually over SSH use cat /etc/openwrt_version and I will get the version
It seems that discovery script may be broken?

OS-Updates slow

All my Linux-based servers are SNMP-extended with "os-updates.sh". Sometimes, this scripts takes ages to complete (sometimes 10+ seconds), which results in a time-out on the poller script.

Result: Application OS-Updates will be remove and added later, when the scripts finishes in time, next time the poller requests this value.

As a suggestion/feature-request/discussion, I propose the following procedure:

1. Load the value of "os-updates.txt"
2. Immediately return this "old/previous" value
3. Check for updates in the background and save this to the "os-updates.txt"

Pro: Script return immediately, no time-outs nor high poller-times
Con: The returned value is "old", as in: the previous value.

What do you guys think? Is this acceptable? A improvement?

If so, I could rewrite the "os-update.sh"!

smart script does not go well with enterprise devices

The smart script expects quite a number of vendor specific attributes to be printed by smartctl -A.

However, in many circumstances, especially on disks run by some Enterprise host controllers like LSI Megaraid, often only general information is printed and not a single "numbered" vendor specific attribute is listed. The result is that the smart script returns an array of "null" and "0" values, totally unusable.

The script should detect the general absence of the character sequence "Vendor Specific SMART Attributes" (or alternatively "SMART Attributes Data Structure"), e.g.when it is called with "-g" and warn the user that monitoring wont work here.
Alternatively there could be a fallback mode in the script, that uses "smartctl -a" instead of "smartctl -A" to extract at least basic health info like errors corrected/uncorrected, temperature and such.

Portactivity returning only zero values

Hello,

I found out that the compare string is wrong in portactivity extend script for snmp, it is comparing for example http with 80 which will not be equal ever.

Best regards.

[Feature Request] Postgres Graphing

Hello,
I would like to see some sort of graphing for postgres similar to what is available for mysql, I am not a programmer so I wouldn't be able to help. If someone is able to do this without a lot of effort it would be greatly appreciated.
Thanks

LibreNMS detects wrong PHP version via validate.php?

Hi,

LibreNMS worked fine on my old server. But, when it's being migrated to a new server, it dectects wrong PHP version via running the file validate.php, output:
Component | Version
LibreNMS |
DB Schema | ?
PHP | 5.4.45
MySQL | ?
RRDTool | 1.3.8
SNMP | NET-SNMP 5.5

[FAIL] Composer has not been run, dependencies are missing [FIX] composer install --no-dev

My old server:

• OS: CentOS 7.x
• PHP: 7.0.23
• LibreNMS: 1.32

My new server:

• OS: CloudLinux Server release 6.9
• PHP: 5.6.4 (with multi-PHP version support)
• LibreNMS: 1.39

Besides, when i run the command "composer install --no-dev" on my new server, it output with nothing (does not automatically install additional PHP packages).

Wrong comparison in zfs-freebsd

On line 118 of zfs-freebsd, the condition $sysctls->{"kstat.zfs.misc.arcstats.size"} >= $sysctls->{"kstat.zfs.misc.arcstats.size"} is checked.

It will in fact always return true, so perhaps one should double check what condition should be evaluated here.

I don't know ZFS stats in detail myself but it certainly doesn't look like it is the expected behaviour, given that an else statement follows right after.

Cannot run bind extension

I cannot run bind script as snmp extend as guided in http://docs.librenms.org/Extensions/Applications/#bind9-aka-named. When I try to use snmpwalk to test extend, i see an errror: "rndc: error: open: /etc/bind/rndc.key: permission denied" . I think we get this error because bind(named) service run as 'bind' user (Ubuntu) but snmp extend run as 'snmp' user. How to resolve it without add snmp user to bind group?

apache-stats.py causes IndexError on Ubuntu 16.04 Apache 2.4

Hi,

When I run apache-stats.py on my Ubuntu 16.04/Apache 2.4 server I get this error:

Traceback (most recent call last):
File "/etc/snmp/apache-stats.py", line 67, in
params[fields[0]] = fields[1]
IndexError: list index out of range

Looking at the output of server-status, I can see that not every line follows "key : value".

My inelegant solution was to add a try catch block starting line 61:

	else:
		# just store everything else
		params[fields[0]] = fields[1]

        else:
                # just store everything else
                try:
                        params[fields[0]] = fields[1]
                except:
                        params[fields[0]] = ''

ceph poolstats - IOPS missing

Hi,

running ceph version 12.2.1 the IOPS are missing in the poolstats output using
the librenms-agent/agent-local/ceph Script.
(Which leads to "0" values in the librenms-rrd files and no graphs for the IOPS)

I think it's a problem with the expected value "op_per_sec" which seems to be
splittet into "read_op_per_sec" and "write_op_per_sec"

• Manually invoking the ceph osd pool stats command

root@ceph03:~# /usr/bin/ceph -f json osd pool stats
[{"pool_name":"rbd","pool_id":0,"recovery":{},"recovery_rate":{},"client_io_rate":{"read_bytes_sec":2321507,"write_bytes_sec":139985,"read_op_per_sec":566,"write_op_per_sec":0}}]
root@ceph03:~#

• Using this ceph Script

root@ceph03:~# /usr/lib/check_mk_agent/local/ceph  | head -n3
<<<app-ceph>>>
<poolstats>
rbd:0:139985:2321507
root@ceph03:~#

• With slightly modifications

root@ceph03:~# /usr/lib/check_mk_agent/local/ceph_TF  | head -n3
<<<app-ceph>>>
<poolstats>
rbd:598:1222483:2304971
root@ceph03:~#

• diff

root@ceph03:~# diff /usr/lib/check_mk_agent/local/ceph /usr/lib/check_mk_agent/local/ceph_TF
65c65
<             o = p['client_io_rate']['op_per_sec']
---
>             o = p['client_io_rate']['read_op_per_sec'] + p['client_io_rate']['write_op_per_sec']
root@ceph03:~#

Maybe someone can verify this?
I'm not even sure if this is the right place to ask or to report this issue.

Thanks!

Thomas

Proxmox agent doesnt work

Hi,

When I start /usr/lib/check_mk_agent/local/proxmox , it say keys on reference is experimental at /usr/share/perl5/PVE/API2Client.pm line 142. <<<app-proxmox>>> virt-01b 105/net0/4271661/1235810/teamviewer.econcept.local 500 Configuration file 'nodes/virt-01b/qemu-server/101.conf' does not exist

does anybody know ho to solve this ?
Thank's !

Version :

pve-manager/4.2-2/725d76f0 (running kernel: 4.4.6-1-pve)
librenms fresh installed from today on ubuntu 14.04

no ceph data in librenms

Ceph data is definitely being returned by the agent as you can see here: http://pastie.org/pastes/10619128/text?key=xbk7mopnipjpgcdi8rfmnw

but no data available in librenms: http://screencast.com/t/tedvrTzH

No idea why its saying RRD Disabled at the bottom either of the poller.php output.

Apache Agent Fails

Hi,

When I try to run the apache agent (agent-local/apache), all I get for an output is,
Data fetch failure.

Is there a way to help debug this?

Thanks!

ntp-server.sh/ntp-client.sh incorrect values

This relates to ntp-server and ntp-client application poller scripts.

This issue is mostly just a placeholder issue as I've done some work on these scripts and I plan on PRing them later.

It seems the output from ntpq -c rv that these two scripts look for can vary slightly in that an extra field sometimes appears which throws off the ordering of values that these two scripts use - resulting in incorrect data being reported as everything position shifted by 1

For example

$ ntpq -c rv | grep jitter
tc=10, mintc=3, offset=-0.313, frequency=0.081, sys_jitter=4.719,
clk_jitter=0.341, clk_wander=0.000

vs

$ ntpq -c rv | grep jitter
mintc=3, offset=-0.696, frequency=16.329, sys_jitter=5.306,
clk_jitter=0.594, clk_wander=0.061

Notice the existence of tc=10 in one but not the other.

ntp-server.sh currently works with the first snippet, but the second one results in "frequency" being used as the value for "offset" etc.

My PR primarily will address the issue at hand here, but it does involve a complete rewrite of the two poller scripts - namely because I couldn't work around this issue with using the for loop as it relied on specific placement.

I also don't hard-code binary names which makes it easier to use on other Distros (The original ntp-server.sh this will replace had to have some modifications to paths in order to run on a Raspberry Pi)

I've duplicated the output of the original so this shouldn't affect existing polling logic from librenms but If someone more knowledgeable in ntp can verify the correct use of the following that be appreciated

ntp sys_jitter is used for $jitter
ntp clk_jitter is used for $noise
ntp clk_wander is used for $stability

Postgres agent not displaying any elements in UI

The postgresql agent is not displaying any graphs in the UI under 'applications->postgresql' under device.

When viewing the graphs under 'apps', it shows as blank graphs

Graphs for other applications correctly display data.

I have added

extend postgres /etc/snmp/postgres

to the snmpd.conf and restarted the snmpd service.

When I manually run /etc/snmp/postgres I get the correct and expected output of postgresql stats.

When I manually invoke a poll of the host using poller.php I notice the output does not include postgresql:

#### Load poller module applications ####
 nginx mysql

>> Runtime for poller module 'applications': 0.9013 seconds with 104376 bytes
#### Unload poller module applications ####

The timezone fail issue is strange - but the system functions fine without it, I've tried fixing it by setting the value and restarting php-fpm but it did not resolve issue - don't believe that to be related to this issue.

deb/rpm/etc packaging?

Any chance we can get librenms-agent packaged in a way our package managers can be aware of it? A PPA/repo might be a good idea too, so we can easily get updates for it too.

The manual steps of installation now exist outside typical software management practices in many open source OS distros.

dhcp-status.sh: fixed paths

dhcp-status.sh contains lots of fixed paths, and thus does not work on debian.

agent (mysql) accidentally stop after successfully graph in the last 24 hours

Hello!

I've installed and running MySQL monitoring using LibreNMS and follow the instructions, the graph was successfully on the dashboard but I don't know why it is accidentally stopped.

I've tried to check the snmp result by running this command: snmpwalk -c public -v2c ip.ad.dr.es .1.3.6.1.4.1.8072 it's success and the result was valid.

how to include graphs from remote host

I want to make something like:

• remote host with monitoring tools for hardware that don't expose their values via snmp or something usual (like emc storages, hp blade online admin modules etc).
• "import" that graphs to the "real host" in librenms, ie:
  • add the real emc storage processor in librenms (but nothing usefull is available)
  • configure remote host with naviseccli (tool from emc to get data out) and export it via snmp (if possible, if not is there another way?)
  • "import" the remote host data/graphs to the real emc storage processor under librenms.

is this doable?

zfs-linux issue for CentOS7

zfs-linux calls /usr/bin/python3 and requires python3 >= python3.5 .
However, the typical repository for python35 does not install python35 at /usr/bin/python3.

If possible change !#/usr/bin/python3 to #!/usr/bin/env python3 in zfs-linux.
Add documentation to advise recreation of override for snmpd on CentOS7 systems, e.g.:

/etc/systemd/system/snmpd.service.d/rh-python35.conf

[Service]
Environment=PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/opt/rh/rh-python35/root/usr/bin
Environment=LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64

os-updates broken on OpenSuSE Leap

snmp/os-updates.sh attempts to determine the distribution by checking for the existence of the various package managers, eg. zypper for OpenSuSE, yum for Redhat/CentOS and apt-get for Debian.

OpenSuSE Leap installs an apt-get wrapper that attempts runs the equivalent commands in zypper, but fails to do so correctly in this case.

On OpenSuSE 13.2, os-updates.sh runs the following command and gets a list of updates:

# zypper lu

On OpenSuSE Leap, it instead does apt-get -s upgrade, which the crappy script interprets as zypper --dry-run update:

# apt-get -s upgrade
Loading repository data...
Reading installed packages...

The following 7 packages are going to be upgraded:
  apache2 apache2-devel apache2-prefork apache2-utils libtiff5 perl perl-base

7 packages to upgrade.
Overall download size: 9.2 MiB. Already cached: 0 B. After the operation, 20.1 KiB will be freed.
Continue? [y/n/? shows all options] (y):

and waits for input from a non-existent user.

This could be fixed by re-writing os-updates.sh to instead read /etc/os-release to determine the distribution and run the appropriate package manager. I believe this file should exist on any modern systemd based distribution - but may cause problems with older distros.

Alert Rules - SQL Error 1046 - Syntax Error

Dear fellow users,

We have a number of installation of LibreNMS. There work separately and update frequently. Recently a review of the librenms.log file revealed a significant number of the following SQL message.

We have started to investigate this problem . The NMS continues to poll the estate. We will aim to marry up the SQL statements which are executed against the database and update the thread.
If anyone has experienced a similar error message, please advise.
As far as we are there have been no changes to the ruleset.
Thanks,

Scripts from documentation missing in repo

Hi all,
based on the documentation there should be some scripts for e.g. monitoring ntp-client and server but they are not in the agent-local folder and it's also not possible to enable them because there is no repository. So it looks like there is something missing or am I doing something wrong?

Best regards,
Markus

Proxmox agent uses deprecated module

PVE::API2Client was removed in PVE 4.4-6. Also see this commit.

This breaks functionality with the Proxmox agent as it throws a Can't locate PVE/API2Client.pm error now.

fail2ban not updating

Hi there,

i don't get fail2ban application to get updated.

i tried:

./poller.php -h host -d -r -f -m applications

and get:

unbound graph is empty

I followed every step to install agent on target unbound server, and setup on librenms server. But still no luck.
Here is :

make smart plugin work behind raid controllers

Would be nice to have it accept parameters such as -d megaraid,0 to allow it to read smart data behind LSI based controllers.

Memcache Missing values !!

We've recently installed librenms agent for memcached and graphs are already started to display but even the stats are there they don't look to be very useful. All important stats are missing such as , cache hits / cache miss / current connections. I can also see that executing memcached plugin from terminal provides these outputs but somehow graph of these values are missing : http://prntscr.com/b040tf .

ntpd stats non functional

apcUPSd values mixed up

I have succesfuly installed https://github.com/librenms/librenms-agent/blob/master/snmp/ups-apcups on my servers. The values reported in the JSON are correct.

The web interface however mixes these values up, it shows 13 for charge (should be time_remaining, shows 57,2 for charge (should be load) and shows 100 for battery_voltage (should be charge).

JSON:
{"version":1,"error":"0","data":{"time_remaining":"13.0","battery_nominal":"48.0","charge":"100.0","nominal_voltage":null,"input_voltage":"223.2","battery_voltage":"55.1","load":"57.2"},"errorString":"apcaccess exited with 0"}
