Monitoring PPS (Packets Per Second) in Zabbix

I will give an example of monitoring PPS (Packets Per Second) on network interfaces in Linux.
In order to calculate the number of transmitted packets per second on the network interface, create two simple scripts, the first to calculate the transmitted packets:

Monitoring Asterisk in Zabbix

We will monitor Asterisk through Zabbix agent, for this we install it on the same machine as Asterisk.

Tracking file changes via Zabbix

I will give an example of checking the integrity of a file through checksum calculation using Zabbix agent.

How to solve the error “Unknown Object Identifier (Index out of range: XXX (ifIndex))”

Once I made a Zabbix template for drawing traffic graphs from GPON ports on Huawei SmartAX MA5683T.

From Linux, I looked at the interface indexes with the command:

Description of Zabbix agent configuration

In this article I will describe the possible parameters of the configuration file of the Zabbix agent.
The symbol “#” means that the parameter is commented out and is the default, that is,
you can not specify it.

Monitoring CPU usage in Zabbix

I will give an example of monitoring the use of each processor core using Zabbix.

Monitoring current RX and TX network interface buffers in Zabbix

One day after restarting the Ubuntu server, due to the long start of a large number of network interfaces, my script which increased the values of the buffers and also performed other settings was performed ahead of time, respectively, the changes did not apply and I found out about this problem only after 24 hours, so I decided monitor current RX and TX buffers.

IPTables rules for Zabbix

Suppose on the default server INPUT DROP, then I will give an example of the rule for Zabbix agent:

Examples of Items for Zabbix

In this article I will give some examples of items for Zabbix agent and server.

Here is an example of counting the number of active processes (Element type is Zabbix agent, so I often count the number of processes nginx, apache2, sshd, named, radiusd, etc., and for a value of 0 you can make a trigger that the process does not work):

Zabbix notifications by phone via Asterisk

One night at the station, the air conditioners turned off and the temperature started to rise, naturally, I received email notifications on the phone, but since it was night, I only saw them in the morning, so it was necessary for such an emergency to quickly make the possibility of phone call notifications.
