Discussion thread for official Zabbix Template Asterisk

[rsafin]

Hello. Could you share the AMI output of commands "ss7 show channels" and "dahdi show status"? Your collaboration would help to improve the template. Thanks.

Hello, I could not provide you AMI outputs, because Zabbix server don't connect to AMI interface, received 500 error. I think the reason is in Asterisk version.

Hello, I could not provide you AMI outputs, because Zabbix server don't connect to AMI interface, received 500 error. I think the reason is in Asterisk version.

Then I don't understand how you're using the template.
Could you show console output of commands "ss7 show channels" and "dahdi show status"?

I don't use zabbix template, My zabbix server received data using custom scripts on monitored server.
Command outputs you can see in snapshots.

How do you discover E1 ports or analog (FXO) ports?

How do you discover E1 ports or analog (FXO) ports?

I will describe all scheme.
1. I have several PC with E1 cards(physical cards), each card have 4 E1 trunks. For example we take PC with 16 E1 trunks.
2. E1 trunks working through Asterisk 11.25.1. And monitored PC have Zabbix_agent v. 2.2
3. Zabbix server have version 5.0
4. In monitored PC were created 2 python scripts, which execute asterisk command and write the result in separate text file.
- 1-st script checks status of asterisk. And write in text file number 1 - if asterisk running, number 0 - if asterisk down. And makes it one time in a minute by crontab. Zabbix agent read text file one time in a minute, get number and send it to zabbix server. Zabbix server biult grafs and statistics.
- 2-nd script cheks status of E1 trunks by following command "/usr/sbin/asterisk -rx 'dahdi show status' | grep OK | wc -l > /etc/zabbix/scripts/dahdi.txt" in this way script write in text file number 16 - that means 16 E1 trunks are UP. The same action as previous script send info to zabbix_server each minutes.
- Also 2-nd script checks active E1 channels by command: "/usr/sbin/asterisk -rx 'ss7 show channels' | grep Connect | wc -l > /etc/zabbix/scripts/ss7.txt" In this scenario script write in a file number of active channels.
Aster command outputs you can find in previous message.

First, I'd like to thank everyone over the years who posted to this forum. While the Zabbix documentation is very useful, seeing actual real-life examples in context really helps.

To that end, I modified the 5.2 template to add a new value. In our case, we need to know not just how many channels are active per SIP trunk, but the sum total of all active channels across all SIP trunks.
Added new data value: "Asterisk: SIP all trunks active channels" (asterisk.sip.all_trunks_active_channels)
Added two new triggers (and Macros) for above, both a warning threshold and a max threshold.

In the process, I also addressed a minor issue that only affects those of us foolish mortals who use SIP trunk names that are longer than 16 characters. The "fix" is only useful if your SIP trunk names do not have unique characters at the end of them because the "core show channels" command used by the template to get a list of active channels only provides the first 16 characters.

I've attached the YAML if anyone is interested (just do a compare/diff vs. the 5.2 YAML to see what I changed/added). I had to zip it up so that the forum would allow me to attach it.

Hello. The official template is changed. Now it uses the "core show channels concise" command to get a list of active channels with full names. Also added items sip.active_channels, pjsip.active_channels, iax.active_channels. https://support.zabbix.com/browse/ZBX-19344
But I doubt that trigger for total active channels of all trunks is useful. It may never get fire. The template has a trigger for active channels of each trunk. You'll always know that the free capacity of the trunk is finished or closed to that.
The trigger for total maybe makes sense only if you have a call balancing between trunks.

Glad to hear that the Zabbix team has updated the template. Our SIP provider does not limit active channels per trunk. Instead, they have an overall total limit, hence why we needed a data value (and, more importantly, triggers/macros) to monitor that sum of active channels across all trunks. We did test it, varying the number of active channels per trunk, but changing the total active channels across all trunks together, and it worked like a charm.

Hello all, Zabbix version 5.4.0, latest template. Everything work OK, but, all time triggered "Asterisk: has been reloaded (uptime < 10m)" In graph view negative values.

I still at the same point, every connection test was well succeded except for the connection (and data acquisition) of the zabbix-asterisk plugin.

Unfortunately, read permission is not enough. Asterisk requires "system" and "command" write permissions to get the AMI response for "CoreStatus" and "core show channels" requests.
