Check HPE ProCurve

Service Monitoring
1

Hi Icinga Community,

I’m new here and tried to modify an existing check to monitor HPE switches.
Hopefully someone can help me solve the problem or give me hints.
Problem:

  • SNMP OID works with Paessler SNMP Tester
  • in icinga the check indicates that there is no OID.

to my project

Thank you in advance!

Hi,

try it the manual way - run snmpwalk/snmpget on the CLI and check whether the OIDs are available. It may be a permission or protocol problem too.

snmpwalk -v2c -c public localhost .1.3.6.1.2.1.47.1.1.1.1.2.1

Cheers,
Michael

Hi Michael,

thanks!

snmpwalk -v2c -c public IP-address .1.3.6.1.2.1.47.1.1.1.1.2.1

I just tested it and with this command it works. But I don’t understand why the check isnt working?

Hi,

the plugin’s code is hard to read, I would start investigating in this line …

if (!defined($s->get_request($oid_systype))) {

And add more verbose logging, e.g.

use Data::Dumper;

print Dumper($s);

for connection tests, likewise read the docs for get_request().

Also, you didn’t show how you call the plugin on the CLi, please add that.

Cheers,
Michael

“if it was hard to write, then it should also be hard to read” :smiley:
Jokes aside, it’s my first code… still have to learn a lot :slight_smile:

To test, I call the plugin with this CLi command:

root@icinga:/usr/local/nagios/libexec# ./check_hpe_procurve.pl -H IP-address -C public

output:

WARNING - SNMP OID CPU LOAD does not exist|

planned output:

OK - HP JXXX Switch - CPU LOAD: x% - MEMORY: x bytes FREE - FAN STATUS: x - PSU1 STATUS: x - PSU2 STATUS: x - TEMP STATUS: x - SYS TEMP: x °C -

Thanks, I will take a closer look at the docs.

Hi,

I’m used to several Perl styles, and have adopted one for the manubulon plugins with perltidy, you might want to have a look at this. Your style isn’t bad at all, just needs some more formatting love :slight_smile:

One thing which differs to the snmpwalk plugin is the protocol. The argument parser allows to specify the version, but sets this to 2 if not given. Try the exact plugin call as you would do from the snmpwalk.

Also, don’t test as root but as the icinga user.

sudo -u icinga /usr/local/nagios/libexec/check_hpe_procurve.pl -H IP-address -C public --version 2c

Cheers,
Michael
