Monitoring total connections on F5

AH, now i know what you want.

 

If you want to monitor a specific node and don`t have the oid yet there´s a bit more work to do. I will write it as easy as possible.

 

Step 1: search the "global" MIB OID for the Node ServerCurrConns attribute which is .1.3.6.1.4.1.3375.2.2.4.2.3.1.9.

 

Step 2: write down the Partition Name which is used on your F5, for example the default ist "Common" so write down /Common/ (don't forget the slash in front and at the end)

 

Step 3: get the exact server name, for example "production_Server_1"

 

Step 4: combine it -> /Common/production_Server_1

 

Step 5: count the letters and write it down: 27

 

Step 6: go to the text to decimal converter of your choice or do it by hand ( Wikipedia ASCII Table) and convert the whole string into decimal with a . (dot) as separator.

 

our example /Common/production_Server_1 in decimal = 47.67.111.109.109.111.110.47.112.114.111.100.117.99.116.105.111.110.95.83.101.114.118.101.114.95.49

 

Step 7: combine everything -> globalMibID.NumberOfLetters.decimalServerName

 

so our string looks like this: .1.3.6.1.4.1.3375.2.2.4.2.3.1.9.27.47.67.111.109.109.111.110.47.112.114.111.100.117.99.116.105.111.110.95.83.101.114.118.101.114.95.49 Step 8: check the oid with an snmpget or snmpwalk .. if it doesn't work check for clerical mistakes (case sensitive!)

 

Step 9: add it to your management system..
