Linux HP Proliant SNMP Agent setup

I wanted to put together a quick post on configuring the hp-snmp-agent and hp-health agents on HP Proliant servers using Linux. I stumbled across the need for this while working on a project to implement Icinga to monitor server hardware via SNMP.

First things first, check that you are running a compatbable HP Proliant G series. The current stable relase of both hp-snmp-agent and hp-helath only work with G5+. This is important to keep in mind because I ran into this issue when trying to install both agents on a G4 Proliant. The dpkg install would fail because it cannot start the hp-health agent under a G4 Proliant. I am installing the agents ontop of Debian 7.

      1. Let’s download the packages, check http://downloads.linux.hp.com/SDR/repo/mcp/debian/pool/non-free/ for latest versions
      2. You will need snmp, snmpd, and some other library files before install the packages.
      3. Now install the two(2) agents. Start with hp-health first, then install hp-snmp-agent

        • If dpkg complains about any missing packages, just do a apt-get -f install should take care of that.
      1. Now, we need to reconfigure snmpd. We can do this 1 of 2 ways. Either use the /sbin/hpsnmpconfig script, or edit the /etc/snmpd/snmpd.conf file directly. I’ll edit the snmpd.conf directly, so edit /etc/snmp/snmpd.conf

          • Pretty much, what we’ve done is set 10.10.10.10 as a trap destination, and an allowed poller(can perform SNMP walks/queries)
          • We’ve also set a custom community string mycommunitystring, this is usually public by default
          • Setting sysContact and sysLocation, which are RFC standard SNMP OID
            OID 1.3.6.1.2.1.1.4 == SysContact
            OID 1.3.6.1.2.1.1.6 == SysLocation

         

          • The dlmod cmaX is something the hpsnmpconfig script adds. I believe it allows the SNMPd to communictate with hp-snmp-agent

         

          • One last thing in the snmpd.conf file. Depnding on what Distro you are using and version of snmpd, look for the line udp:127.0.0.1:161 and change it to udp:161. For somereason, SNMP queries won’t work unless this is changed.

         

         

 

      1. Now, restart all services involved.
      2. Let’s test. Must be done on server 10.10.10.10, or whatever IP you used.

        • The above commands should output you sysContact and sysLocation
      3. Let’s also test the hp-snmp-agent OIDs, to make sure it is properly integrating

        • The first test should output the Proliant Product Platform, such as “ProLiant DL380 G6”
        • The second, should output the status as an integer of the Power Supplies. (1 = other, 2 = ok, 3 = degraded, 4=failed)

Optional

To take it a step further, I recommend downloading this nagios script, and executing it against the HP Server you just set up. https://exchange.nagios.org/directory/Plugins/Hardware/Server-Hardware/HP-%28Compaq%29/check_hp/details
