graph alphanumeric value
Hi all,
this is my first post, i came from Zenoss experience and i need to understand how to graph a non numerical value…i try to explain myself better.
with and enteprise oid i grab with snmp from my switches their temperature but the value is “36.4C”.
so with zenoss i use a snmpwalk script and with text managing tool as “sed” i grab only numerical value extrapolating from mixed alphanumeric value.
so in Pandora how to graph a value that came in that format?

It pretty the same, you have several options. Easier is probably run the same script in a softwre agent running a linux.
Integrated SNMP Network monitoring assume SNMP return you a integer, so it’s not a valid option.
Another way is to write a plugin server (the best option, but the most complex), that includes create a small script which receive as parameter the ip of the device and as other parameter the snmp community. That script will do the magic inside and return only the numerical information.
You will copy the script in the server, will do the registration on the plugin server registration, and will be a “Plugin check” specifically for your needs, able to use in any remote agent you want, like a ICMP Check, or a standard SNMP Check.
Note that plugin server is disabled by default, you need to enable it in pandora_server.conf.
Check for “plugin server” in the documentation for more information.

You’re right, backup extension is an enterprise feature… anyway, you can do it manually, just take a look on other doc. chapters about it.
About the CentosRPM for 3.2.1, we don’t release yet a package for centos, but you can use the tarball for doing the install.
