the plugin "check_xi_service_snmp_linux_storage_o10000" always Critical alert?!

Critical: octet length: 10000 isnnum: 0 0 zero O capital oERROR: Description/Type table : No response from remote host "10.36

Monitor the service with this command
check_xi_service_snmp_linux_storage_o10000!-C tpetng --v2c -m "^/$" -w 90 -c 95 -f!!!!!!!

That might be a modification of a standard command. Our command is check_xi_service_snmp_linux_storage. Can you go to Configure -> Core Config Manager -> Services -> select the service in question, and click on Run Check Command. Then take a screenshot of the test so we can see the full command that is getting passed through.

after ran the command, the output ...


/usr/local/nagios/libexec/check_snmp_storage_wizard_o10000.pl -H 10.36.3.168 -C tpetng --v2c -m "^/ftp01$" -w 90 -c 95 -f
octet length: 10000 isnnum: 0 0 zero O capital o/ftp01: 29%used(602763MB/2048001MB) (<90%) : OK | '/ftp01'=602763MB;1843201;1945601;0;2048001

I see in the command that is failing it is trying to connect to 10.36.3.169 but in your example running the command you are connecting to 10.36.3.168

actually it's 10.36.3.168

don't know why 10.36.3.168 no respond so frequently, what could be the problem?!

Hmm, these are 2 different hosts in your screenshots.

With SNMP you are utilizing UDP packets which certainly are less reliable than say an agents packets that use TCP, but usually they get dropped by a router with network congestion if at all.
