Description :
Checks by snmp v1, v2c or v3 :
- Memory and swap usage on Linux given by Net-snmp.
It checks memory and swap usage independantly : one warning and
critical level for each of them.
- Memory usage on cisco routers or Pix : the
plugin will add all of the memory pool and then checks the warning
and critical levels.
On cisco routeurs, it will add 'IO' and 'Processor' memory
On Pix, it will check the memory used (one memory pool only on Pix).
- Memory usage on HP Procurve switch.
Memory segments will be added then the free memory will be checked.
Vérification de :
- l'utilisation mémoire et swap sur Linux/Net-snmp
- l'utilisation mémoire sur Cisco (routeurs et Pix).
Pour d'autres SE (Windows, AS400), lire la suite.
Checking memory for other os :
AS/400 : use the check_snmp_storage
command to check the RAM
./check_snmp_storage.pl -H <IP>
-C <community> -m RAM -s -w <warn%> -c
<crit%>
Windows : use the check_snmp_storage
command to check the virtual memory (RAM+Swap)
./check_snmp_storage.pl -H <IP>
-C <community> -m "^Virtual Memory$" -w <warn%>
-c <crit%>
