SNMP management of VLC instances

[caduellery]

Hello,

First of all, I want to thank the dev team for this very useful application!
Now the question: I have a VLMa 0.2.0 server controlling 10 streaming servers. All of them are running vlc 0.8.6d instances on Fedora Core 6 systems.
So, at the "Configuration" screen of my VLMa, there are SNMP configs with the OID text boxes already filled with some default values. But, with these values I don't get any result in the graphs available at the "Servers graphs" screen of VLMa. Mind that I've installed snmpd on my servers and can monitor them with using a NMS system, like the JFFNMS (http://www.jffnms.com). The SNMP community configured in VLMa is the same of my NMS, and this one is using SNMP v1 too. In my NMS I can get graphs of CPU, Memory, Memory of VLC instance, and much more... in VLMa the graphs are empty.
BTW, the only data I don't have yet is the "CPU resources used by VLC". The others like CPU, Mem and traffic, I can monitor with the NMS.

So, what is the right OID to use for getting this data? Or, what configuration I have to do to get the SNMP stats of VLMa working fine?

Thanks!

Hello,

Actually, the default SNMP OID of VLMa don't make sense, we should rather have kept those fields empty. I think you should try to find the OID that your NMS system queries and configure VLMa so that it uses those OID. For the non-standard metrics to retrieve such as resources used by VLC, you have to configure it on the SNMP servers' side by binding an arbitrary OID to a shell command such as

Code: Select all

ps -C vlc -o pcpu=

to get the CPU usage of VLC. We know that this is not really convenient and that the result of such a query may be wrong (for example if two instances of VLC are running on the server) that's why we're working on a new system for the next release.

This would really be a nice feature. Is there any release date available for the next release ?

Thanks

Hello,

I can't give you any date but you can try the nightly builds which should be almost stable:
