zabbix-monitoring-programs-execution

The program controls the execution of any programs, scripts or commands OS and sends the execution result to zabbix, and in case of an execution error, it additionally can notify via telegram.

NOTE: Any programs, scripts or commands OS that is controlled by zm.py in the future, I will call - process.

Work logic

Logging is done in stdout.
All zm.py settings are performed through environment variables.
Telegram notifications can be turned off with ZM_TELEGRAM_NOTIF=False. In this case, you will only receive alerts from Zabbix in which you can also set up Telegram alerts, but zm.py has more informative alerts.
Send data to can be turned off with Zabbix ZM_ZABBIX_SEND=False. In this case, you will only receive alerts to Telegram. Send process time execution to can be turned off with Zabbix ZM_ZABBIX_SEND_TIME=False. Only error messages are sent to Telegram. Messages about the successful completion of the process are not sent to Telegram (so that there is no flood).
In case of successful completion of the process, the process execution time and the successful result are sent to Zabbix. The value of successful result is set to ZM_ZABBIX_OK.
In case of the process execution error, execution time = 0 and the unsuccessful result are sent to Zabbix. The value of unsuccessful result is set to ZM_ZABBIX_NOT_OK. You can run zm.py in a Docker container.

Settings

ENV	Default	Description
ZM_DEBUG	False	Enable DEBUG mode? (True or False).
HOSTNAME	Unknown	For Telegram message to see which host this message is from. In Linux, such a variable is usually already set.
Zabbix settings
ZM_ZABBIX_SEND	True	Should app send data to Zabbix? (True or False).
ZM_ZABBIX_SEND_TIME	True	Should app send execution time to Zabbix? (True or False).
ZM_ZABBIX_OK	0	OK value for Zabbix.
ZM_ZABBIX_NOT_OK	1	Not OK value for Zabbix.
ZM_ZABBIX_IP	None	Zabbix server ip address.
ZM_ZABBIX_HOST_NAME	None	Zabbix "Host name". How is the host named in Zabbix. (See picture after table).
ZM_ZABBIX_ITEM_NAME	None	How is the trapped item key named in Zabbix.
ZM_ZABBIX_ITEM_TIME_NAME	None	How is the trapped item for execution time key named in Zabbix.
Telegram settings
ZM_TELEGRAM_NOTIF	True	Should app send telegram alerts? or log messages only to stdout. (True or False).
ZM_TELEGRAM_TIMEOUT	10	Telegram connection timeout.
ZM_TELEGRAM_BOT_TOKEN	None	Telegram bot token. It usually looks like this 1470616475:AAHFSvznxxLTDedQBSiRVrYVP49ixkghpRT. You need to create a bot in Telegram using BotFather and you can also get a bot token there.
ZM_TELEGRAM_CHAT	None	Telegram chat (ID) to which the bot will send messages. If this is a private chat, then usually the ID looks like a positive number. If it is a channel or group then ID is a negative number.

NOTE: Parameter ZM_ZABBIX_HOST_NAME you can see here

Install and run

Install Python3

Python Download

Customize Zabbix

In this example, ZM_ZABBIX_ITEM_NAME will be called docker-rmi-sh and ZM_ZABBIX_ITEM_TIME_NAME - docker-rmi-sh-time. This name will be written in the Key field.
Create trapped items ZM_ZABBIX_ITEM_NAME and if you need ZM_ZABBIX_ITEM_TIME_NAME.
Create trigger for ZM_ZABBIX_ITEM_NAME with that Expression:
{172.26.12.168:docker-rmi-sh.last()}=1 or {172.26.12.168:docker-rmi-sh.nodata(25h)}<>0
The trigger fires when there was an error while executing the process or when the process has not run for more than 25 hours.
You can see Graphs for items: menu Monitoring - Latest data - Filter.Hosts choose desired host - there is Graph in the item line.
Or you cat create your own graphs.

Settings

You must set environment variables on the computer where the zm.py will run and under the account under which zm.py will run.
There are many ways to define environment variables.

Run

In this example, I write all the necessary variables in file .bash_profile.

export ZM_ZABBIX_IP="172.26.12.86"
export ZM_ZABBIX_HOST_NAME="172.26.12.168"
export ZM_ZABBIX_ITEM_NAME="docker-rmi-sh"
export ZM_ZABBIX_ITEM_TIME_NAME="docker-rmi-sh-time"
export ZM_TELEGRAM_BOT_TOKEN="1470616475:AAHFSvznxxLTDedQBSiRVrYVP49ixkghpRT"
export ZM_TELEGRAM_CHAT="123456789"

1) As script

mkdir /usr/share/zabbix-monitoring-programs-execution
cd /usr/share/zabbix-monitoring-programs-execution
git clone https://github.com/MinistrBob/zabbix-monitoring-programs-execution.git .
pip3 install -r requirements.txt
python3 /usr/share/zabbix-monitoring-programs-execution/zm.py <process>

2) As cronjob (or if you use sudo -s or su)

If you use cronjob or if you use sudo -s or su you will need source command

MAILTO=""
0 3 * * * source /home/user/.bash_profile; python3 /usr/share/zabbix-monitoring-programs-execution/zm.py /usr/share/local/docker-rmi.sh 2>&1
