My project required that I grab the QOS drops from the different class-maps on multiple routers and then feed them into a Splunk dashboard. Scripting the multiple snmpwalks and outputting to CSV for ingestion by Splunk was the best way I had at my disposal.
Introducing get_qos-v3.sh
Usage : get_qos-v3.sh Customer Host_IP Host_Name Priv_Proto(DES/AES)> get_qos-v3.sh Cust1 10.10.10.4 USA-Winslow "DES"
This script will output the following:
> cat /nsm/snmp/customer/Cust1/Cust1-10.10.10.4-qos.log
07-03-2014 17:00:01,Cust1,10.10.10.4,Winslow,class-default,sla,0
07-03-2014 17:00:01,Cust1,10.10.10.4,Winslow,class-default,class-default,0
07-03-2014 17:00:01,Cust1,10.10.10.4,Winslow,class-default,control,0
07-03-2014 17:00:01,Cust1,10.10.10.4,Winslow,class-default,media-ports,25
07-03-2014 17:00:01,Cust1,10.10.10.4,Winslow,MAP-QoSParentPolicy,class-default,25
My requirements dictated that I had customer separation as well as individual sites listed separately. Remove them if you dont need! (Or ask me to edit them out of the code)
Before you run the script you will need to edit the top part of the script to match your SNMPv3 settings, and log file locations. User, auth_passwd, priv_passwd and log_file are the only variables you should need to set. Please note that user and auth_passwd need the single (') quotes around them, while priv_passwd does not.. It was extremely frustrating troubleshooting those quotes.
This script assumes SNMPv3. If you need SNMPv2 functionality, write me and we can work up a new command line.
