Query on elasticsearch userparameter

Hi,
I'm new to zabbix. I was trying to understand the userparameter for elasticsearch defined here at
https://github.com/scoopex/zabbix-agent-extensions/blob/master/extension-files/agent-config/zabbix_elasticsearch.conf

From where are we passing these args to script
UserParameter=elasticsearch[],/usr/bin/zabbix_check_elasticsearch $1 $2
These args are being passed through this elasticsearch[] key but where are we providing the values.
Please help me to understand these $1 and $2.

Automatic CI Builds and automatic APT Source

To ease the development, testing and distribution of the zabbix-agent-extensions the entire package should be procressed automatically.

Testing:

• Test the package on recent CentOS, Ubuntu and OpenSuse Systems

Release Creation:

• Upload as GITHub release
• Upload to a package server

Availabilty status not displayed

Hi,
I have this template and the extensions working, but there is an issue with the availability display icon at hosts view.
When the agent is active and working, the icon should be green. When activating the template Custom - OS - Linux, all seems to be working, but the icon shows greyed out.
Could it be a problem with color configuration of the template?
Thanks.
Jota.

FEATURE: Monitor pagecache hitrate

For proper memory sizing of virtual machines it will be very useful to get a impression of the amount of successful pagecache lookups.

MDRaid Sync activity is not correctly notified

UserParameter don't work, and don't know why?!

Hi I have some problem:
UserParameter=varnish.stat[*],(test -f /usr/bin/varnishstat && varnishstat -1 -f $1 | awk '{print $$2}')
is not working, on zabbix serwer show "cannot convert value to numeric type"
when I want to execute (test -f /usr/bin/varnishstat && varnishstat -1 -f $1 | awk '{print $$2}')

`varnishstat: option requires an argument -- 'f'
Usage: varnishstat

Options:
[-1] Print the statistics to stdout
[-f ] Field inclusion glob
[-h] Usage help
[-j] Print statistics to stdout as JSON
[-l] Lists the available fields to use with the -f option
[-n

`

echo "(test -f /usr/bin/varnishstat && varnishstat -1 -f$1 | awk '{print $$2}')" (test -f /usr/bin/varnishstat && varnishstat -1 -f | awk '{print 33062}')
how it should work?

Elasticsearch Python script broken

The Python script for Elasticsearch doesn't output values any more.

This bug seems to be introduced with 88909dc and the switch to Python 3.

Add support for systemd/chrony timedatectl monitoring

NTP monitoring currently depends on the installation of ntpd.

Enhance the current implementation to automatically discover the type of the ntp-synchonization and provide suitable measures.

Systemd-timesyncd implements SNTP, not NTP, hence multi-server support is out of focus. If you want a full NTP implementation, please use ntpd or chrony.

Improve packaging

The way to package this product should be improved.

• automatic testing
• automatic upload of packages to github
• specify all dependencies

Help is very welcome :-)

zabbix_discovery_filesystems help contains erroneous JSON example

Hi,

First of all I would like to thank you for this outstanding and absolutely amazing work you shared.
I like the approach taken, how well it's all designed and structured. Thank you!

Regarding the issue:
/usr/bin/zabbix_discovery_filesystems --help

Output contains:

Example json configuration file:

i.e. /etc/zabbix/item_zabbix_discovery_filesystems.json
---
{
  "regex_includes_name": [
    ".*"
  ],
  "regex_includes_type": [
    ".*"
  ],
  "regex_excludes_type": ["nfs", "nfs4", "nfsd", "cifs", "autofs", "binfmt_misc", "cgroup", "cgroup2", "configfs",
                            "debugfs",
                            "devpts", "devtmpfs", "efivarfs", "fusectl", "fuse.gvfsd-fuse", "hugetlbfs", "mqueue",

}
---

The problem is that this example is missing at least empty JSON structure "regex_excludes_name": [],
Which results in JSON parse complains:

Traceback (most recent call last):
  File "/usr/bin/zabbix_discovery_filesystems", line 171, in <module>
    if check_match("exclude", filesystem_name, config["regex_excludes_name"]):
KeyError: 'regex_excludes_name'

It also has JSON syntax error - comma after last element "regex_excludes_type", which produces JSON parsing error:

# zabbix_agentd -t "vfs.fs.discovery"
vfs.fs.discovery                              [t|Could not parse JSON config file

Please clarify installation from rpm/deb package

Hi. I am new to zabbix and this module (about 1 hour) but quite good general linux maintenance.

I successfully installed zabbix server on my webserver.

1. Must I also create localhost as an "agent" machine on zabbix server?
2. I executed:
   yum localinstall zabbix-agent-extensions-2.4.36-1.noarch.rpm
   which packages should I then install/enable/start?
3. When importing a template what would be standard option for a agent/server on the same single machine i.e. do not create new host etc.?

Package source

Try to find a offical package source service, where the packages can be published.

Implement a smtp/imap roundtrip

To check the proper function of a mail setup, provide a possibility to do a two way check:

• send a mail using smtp over a remote service (i.e. gmail) and check if the mail can be received on your personal setup
• send a mail using smtp over your personal setup and receive it on remote service (i.e. gmail)

As soon as this file is removed from directory zabbix agent start without any issue.

Please kindly advise.

Thank you!
