Plugin snmp doesn't find snmpget on SLES

[mdicss]

Hi
I would like to use plugin snmp (compiled version ) on SLES 15.4. net-snmp is installed. We have:

# which snmpget
/usr/bin/snmpget

# /usr/bin/snmpget -V
NET-SNMP version: 5.9.3

When I call snmp, I get a message, that snmpget is not found:
./snmp -H xx.yy.zz.uu
snmpget not found

Any idea how to fix this?

Thanks for any hints, regards
Matthias

can you send the output of command -v snmpget; echo $?? this is how the plugin checks if it can find snmpget, see

monitoring-plugins/check-plugins/snmp/snmp

Line 201 in 61a32aa

success, result = lib.shell.shell_exec('command -v snmpget')

Looks ok?
# command -v snmpget; echo $?
/usr/bin/snmpget
0

Seems that the user under which the plugin is running does not have access to the snmpget command. Try using sudo -u icinga snmpget.

Hi Markus

Thanks a lot for your fast and good help!
I narrowed down the problem in the meantime. In CentOS which we used until now, there is a shell skript '/bin/command', which calls the shell command 'command'.

# cat /bin/command
#!/bin/sh
builtin command "$@"

This skript is missing in our sles 15.4 installation. So I copied it from CentOS to Sles and it now works.
As searching for command 'command' in the net is a bit a problem, I did not yet find, why the skript is missing in sles.
Another aspect of the problem is, that the user icinga is a 'nologin'-user. So icinga seems not to run inside (ba)sh as (ba)sh has the builtin command 'command'.

Maybe you can change the test in your skripts?

Regards
Matthias

Great, thanks for your tests. So the solution is simple: We stop checking for the existence of snmpget, because when it is called and if it is missing, we later already get a meaningful error message like OS Error "2 No such file or directory: 'snmpget'".
