Checking Switches and Routers like whats up

[Jan Scholten]

Try a generic check like:
define command{
          command_name    check_pix515_if
          command_line    $USER1$/check_snmp -H $HOSTADDRESS$ -C $USER3$ -o  
interfaces.ifTable.ifEntry.ifOperStatus.1 -c 1
}

and use it with a service definition like:
..
check_command	check_pix515_if!1     (for the first port)
and

check_command	check_pix515_if!2     (for the second port)


$USER$ is in the resources.cfg and contains the snmp password

As you can see this will be a lot of snmp checks per switch. you can  
aggregate some Ports and check up to 8 OIDs, i do that for some routers:

#Checks for Linkup on ae02s
define command{
         command_name    check_ae02s_ifStatus1
         command_line    $USER1$/check_snmp -H $HOSTADDRESS$ -C $USER3$ -P  
1 -m ALL -o  
1.3.6.1.2.1.2.2.1.8.16,1.3.6.1.2.1.2.2.1.8.17,1.3.6.1.2.1.2.2.1.8.18,1.3.6.1.2.1.2.2.1.8.19,1.3.6.1.2.1.2.2.1.8.20,1.3.6.1.2.1.2.2.1.8.21,1.3.6.1.2.1.2.2.1.8.22,1.3.6.1.2.1.2.2.1.8.23  
-w :1,:1,:1,:1,:1,:1,:1,:1 -c :1,:1,:1,:1,:1,:1,:1,:1 -l "Linkstatus for  
Vlans is:"
		  }

As a result i have get: Linkstatus for Vlans is: OK - 1 1 1 1 1 1 1 1

If you want to check every Port seperate you'll have a real big service  
overview and a load of checks (slow) what you could do: make every port  
"not activeley checked" and handle incoming snmp traps (Link up/Link down)  
and use a script do determine which port should be set up or down. use  
freshness to check at least .. say every two hours if the current state  
ist still ok (so no Up/Down Trap received). See the doc i sent yesterday!
