Cgroup metrics unsupported

On my server, the /sys/fs/cgroup/memory/system.slice/ directory does not exist, but /sys/fs/cgroup/memory/ does with the following content:

Feature requests

Thanks Ryan for publishing your systemd module 👍 . I made similar one based on sd-bus API of systemd a few months ago, but I didn't publish it. There is published only cgroup version as a part of docker module. I would like to deprecate my systemd monitoring in favor of your systemd module. I would like to see these features:

• Filter unit type in unit discovery
  It will simplify creating of LLD rules per unittype. systemd.unit.discovery[<unittype>] - type of discovered unit: service, socket, device, mount, automount, ... Default value probably: all.

• Cgroup resource monitoring
  For example systemd services are "containers", so you can read their CPU/mem/IOPs metrics from the cgroups
  systemd.cgroup.mem[fid,mmetric], systemd.cgroup.cpu[fid,cmetric], systemd.cgroup.dev[fid,bfile,bmetric] ,...

Monitoring an custom systemctl process

Hi,
how can I monitor an custom systemctl process?
For example i run a service (java process with parameters) with the command:
systemctl start broker.
It run as:
java -server -Xms24g -Xmx24g -XX:MaxDirectMemorySize=56g -XX:+UseG1GC -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=75....

Thanks

Monitoring Template Systemd Units

How does monitor a templated systemd unit? For example, here's the ClamAV service:

Since Zabbix doesn't like @ in the fields, how does this work?

Then scroll to the "Creating Instance Units from Template Unit Files" part.

Read current slice setting

Some units can use custom slice setting. Use that one for reading of cgroup performance counters (cpu, mem, ....) instead of hardcoded system.slice path. For example:

$  zabbix_get -s 127.0.0.1 -k systemd.unit[[email protected],Service,Slice]
system-getty.slice

Reference: #5

zabbix agent 3.4 unsuported cgroups

I tried to garther some information from the cgroup accounting by service (CPU and mem).

I enabled cgroup inside systemd default config file but the key seems to still be unsuppoted. I am using the provided RPM package (1.2.0 version).

Here is the ouput when trying to retrieve the key.

zabbix_agentd -t systemd.cgroup.cpu[dbus.service,rss]

systemd.cgroup.cpu[dbus.service,rss]          [m|ZBX_NOTSUPPORTED] [Unsupported item key.]
process 26457: arguments to dbus_connection_unref() were incorrect, assertion "connection != NULL" failed in file ../../dbus/dbus-connection.c line 2823.
This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace

Do you have any clue on where the issue could reside ?

Why do you need to check that in parallel to the correspondent NULL?

[1] gcc (GCC) 9.3.1 20200317 (Red Hat 9.3.1-1)

Include instructions for compiling against 3.0.x packaged versions from yum repos

Compiling the agent module:

• Download the exact version of the Zabbix sources that correspond to your running version. Mine is 3.0.9, I put it under /root/src
• yum groupinstall "Development Tools"
• yum install dbus-devel libtool gettext autoconf automake
• ./autogen.sh
• ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64 --with-zabbix=/root/src/zabbix-3.0.9 (omit --libdir switch if 32 bit machine; replace src download path with your own)
• make && make install
• service zabbix-agent restart
• pidof zabbix_agentd to see if it's running properly

Importing template XML into zabbix:

• Edit version tag from 3.2 to 3.0
• Remove empty <httptests /> tag

configure: error: /usr/src/zabbix/include/module.h does not exist

I need to "svn export svn://svn.zabbix.com/tags/4.0.11 /usr/src/zabbix", but this doesn't work.
svn package is no longer available.
I also found that svn was moved to git.

Do you have an idea what that updated command would be?

Thank you!

Template not working with version 3.4

Error: Cannot accurately apply filter: no value received for macro "{#SERVICE.STARTUPNAME}".
https://www.zabbix.com/documentation/3.2/manual/introduction/whatsnew3210

Example:

   {
      "{#SERVICE.TYPE}": "service",
      "{#SERVICE.NAME}": "systemd-sysctl.service",
      "{#SERVICE.DISPLAYNAME}": "Apply Kernel Variables",
      "{#SERVICE.PATH}": "/lib/systemd/system/systemd-sysctl.service",
      "{#SERVICE.STARTUPNAME}": "static",
      "{#SERVICE.CONDITIONRESULT}": "yes"
    },
    {
      "{#SERVICE.TYPE}": "service",
      "{#SERVICE.NAME}": "keyboard-setup.service",
      "{#SERVICE.DISPLAYNAME}": "LSB: Set preliminary keymap",
      "{#SERVICE.PATH}": "/run/systemd/generator.late/keyboard-setup.service",
      "{#SERVICE.CONDITIONRESULT}": "yes"
    },

As you can see {#SERVICE.STARTUPNAME} is missing.

ZBX_NOTSUPPORTED: Unsupported item key

Hi,
I've compiled and installed module. I see the it into /usr/local/lib/zabbix/modules/libzbxsystemd.so.
I changed paramenters info /etc/systemd/systemconf and I reload then zabbix-agent.

If i call (for example) show this error:
[root@zabbix zabbix-module-systemd]# zabbix_get -s <ip-address> -k systemd[Architecture] ZBX_NOTSUPPORTED: Unsupported item key.

Where is my error?

Missing SERVICE.CONDITIONRESULT in template item prototype

On my CentOS 7 system, the results returned by systemd.service.discovery[] do not include the #SERVICE.CONDITIONRESULT property. As a result, no items are created, because the item prototypes in the template include the filter {#SERVICE.CONDITIONRESULT} matches "yes".
Once I removed that condition, the items showed up.

Cannot open cpuacct.stat file

Hi!
I'm getting Cannot open cpuacct.stat file error on systemd.cgroup.cpu[{#SERVICE.NAME},total] item with latest zabbix and centos 7.3

Arguments to dbus_connection_unref() were incorrect

Environment:

OS: 4.4.0-81-generic #104-Ubuntu SMP x86_64 GNU/Linux
zabbix-agent: zabbix_agentd (daemon) (Zabbix) 3.2.7
libdbus: libdbus-1-3:amd64 1.10.6-1ubuntu3.3
zabbix-module-systemd: built from 8d2d52a against zabbix-3.2.7 sources.

Steps to reproduce:

Ask zabbix for a systemd.cgroup.* key.

Expected:

No errors/warnings on stderr.

Actual:

arguments to dbus_connection_unref() were incorrect warning.

Example:

$ zabbix_agentd -t systemd.cgroup.mem[dbus.service,rss]
systemd.cgroup.mem[dbus.service,rss]          [u|520192]
process 14252: arguments to dbus_connection_unref() were incorrect, assertion "connection != NULL" failed in file ../../dbus/dbus-connection.c line 2821.
This is normally a bug in some application using the D-Bus library.```
