SNMP OID for Captive Portal user count

rovshango

Dear Friends,

Does anyone know how to get count of logged users in CP, surely I can see it from status page and RRD graphs.
But I wanna find SNMP OID, so I can create custom graphs in Zabbix as example.

Thank you all in advance.

There is no SNMP OID for captive portal, it's not exposed to the snmp daemon in any usable way.

Hi,rovshango
You can do it in another way, use "UserParameter" method of zabbix.

please check this post for detail.

https://forum.pfsense.org/index.php?topic=70766.msg386632#msg386632

1, Install zabbix agent in package manager, then configure zabbix agent settings in web GUI as you need;
2, create a script, for example /root/CP_total_users, then add "UserParameter" line in /usr/local/etc/zabbix22/zabbix_agentd.conf

UserParameter=CP_users,/root/CP_total_users

3, Create a host in zabbix Web UI for this pfsense box, add the item of custom key "CP_users" in this host;

4, Create graph as you need, Done!

Here is a question about pfsense or zabbix agent.

I am using zabbix to monitor the Captive Portal user count, and the zabbix agent is running by the user "zabbix", I also create the script following @Gertjan 's post. There is a step that I forgot to mention in the last post. I need to change the file permission of "/usr/local/etc/php/extensions.ini" , let zabbix user can read it, otherwise the script will not work when zabbix agent execute it.

chmod a+r /usr/local/etc/php/extensions.ini

but when I reboot pfsense, the file permission restore to default ( -rw–----- ).

how can I keep the change persistent after reboot ?

I will not change the run user of zabbix agent (to root) unless I have to, also I want to know if I modify the zabbix file (/usr/local/etc/rc.d/zabbix_agentd_lts.sh), will it restore to default after reboot too?

No.
The file "/usr/local/etc/rc.d/zabbix_agentd_lts.sh" is part of the package.
Edit it to add some code to change your file permissions.
Of course, reinstalling the package will change the file.
NOT pfSEnse reboot.

Thank you, but I found the first tree lines of the file "/usr/local/etc/rc.d/zabbix_agentd_lts.sh", so it is not suitable for adding custom commands.

#!/bin/sh

This file was automatically generated

by the pfSense service handler.

I also tried to modify it, and it restored to original state after reboot.
Now I will follow this doc Executing commands at boot time, will update here after I finish test.

update:
OK, The "shellcmd option" works well.

Did you get this fixed? I am running into the same issue.
