When using the plugin to poll a Net-SNMP system, it will check the Real Memory as well as the Swap Memory which then requires both thresholds to be set like below.

-w, --warn=INTEGER | INT,INT
warning level for memory in percent (0 for no checks)
Default (-N switch) : comma separated level for Real Memory and Swap

-c, --crit=INTEGER | INT,INT
critical level for memory in percent (0 for no checks)
Default (-N switch) : comma separated level for Real Memory and Swap

Thanks A lot team you got this worked.

Your welcome.
If you do not have any further related questions, shall I mark the post as solved and lock it up?

Check_mem.pl is not giving any performance graph data so not generating graph can you please help.

Can you run the command with the -h flag to see if there is something that needs to be added to enable performance data output

-v, --verbose
print extra debugging information (including interface list on the system)
-h, --help
print this help message
-H, --hostname=HOST
name or IP address of host to check
-C, --community=COMMUNITY NAME
community name for the host's SNMP agent (implies SNMP v1 or v2c with option)
-2, --v2c
Use snmp v2c
-l, --login=LOGIN ; -x, --passwd=PASSWD
Login and auth password for snmpv3 authentication

<authproto> : Authentication protocol (md5|sha : default md5)
<privproto> : Priv protocole (des|aes : default des)
-P, --port=PORT
SNMP port (Default 161)
-w, --warn=INTEGER | INT,INT
warning level for memory in percent (0 for no checks)
Default (-N switch) : comma separated level for Real Memory and Swap
-I switch : warning level
-c, --crit=INTEGER | INT,INT
critical level for memory in percent (0 for no checks)
Default (-N switch) : comma separated level for Real Memory and Swap
-I switch : critical level
-N, --netsnmp (default)
check linux memory & swap provided by Net SNMP
-m, --memcache
include cached memory in used memory (only with Net-SNMP)
-I, --cisco
check cisco memory (sum of all memory pools)
-E, --hp

-f, --perfdata
Performance data output
-t, --timeout=INTEGER
timeout for SNMP in seconds (Default: 5)
-V, --version

Ok, with this plugin you wand to add the -f flag to your command and then it will create performance data

Thanks man,
