h3c switch monitoring by SNMP

[huytq1786]

Dear All
I just installed Nagios Core, and now i would like to monitoring H3C switch by SNMP, But i got error:
(No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_snmp, ...) failed. errno is 2: No such file or directory

this is my switch.cfg file:

check_command check_snmp! -C 123456 -o sysUptime.0

i already configed on H3C switch as: snmp-agent community write 123456

Can you share the full output of the following command executed from the CLI of your Nagios Core machine:

Code: Select all

ls -al /usr/local/nagios/libexec/

It looks like you're missing the check_snmp plugin, which is included with the most recent version of nagios-plugins. I would download the most recent one here, and then re-compile them. https://www.nagios.org/downloads/nagios-plugins/

I verified on my end, and here are the plugins you should see (after compiling 2.1.4) -

Code: Select all

[root@bob libexec]# ls
check_apt       check_flexlm        check_ircd      check_nntps     check_pop      check_ssh     check_wave
check_breeze    check_ftp           check_jabber    check_nt        check_procs    check_ssmtp   negate
check_clamd     check_hpjd          check_load      check_ntp       check_real     check_swap    old
check_cluster   check_http          check_log       check_ntp_peer  check_rpc      check_tcp     urlize
check_dhcp      check_icmp          check_mailq     check_ntp_time  check_sensors  check_time    utils.pm
check_disk      check_ide_smart     check_mrtg      check_nwstat    check_simap    check_udp     utils.sh
check_disk_smb  check_ifoperstatus  check_mrtgtraf  check_oracle    check_smtp     check_ups
check_dummy     check_ifstatus      check_nagios    check_overcr    check_snmp     check_uptime
check_file_age  check_imap          check_nntp      check_ping      check_spop     check_users

It could be you're missing some dependencies and then the check_snmp file will not be compiled.

Please check:

Code: Select all

ls -al /usr/local/nagios/libexec/check_snmp*

To verify if snmp is configured correctly, please try:

Code: Select all

snmpwalk -v2c -c 123456 h3cswitch_ip_address sysUptime.0

[rkennedy]

Thanks @rhassing!

@huytq1786 - if you recompiled once again with the latest version then what @rhassing mentioned is correct, you may be missing pre-reqs.
