Trouble gettng Global Concurrent Connections with SNMP

is this oid applicable?

Hi. I used snmpwalk on the LTM to look for virtual stats. You need to make sure localhost is enabled in your snmp configuration. It usually is by defauilt.

 

 

snmpwalk -v 2c -c public localhost F5-BIGIP-LOCAL-MIB::ltmVirtualServStat

 

 

If you want to start with an OID number, you can try this:

 

 

snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.3375.2.2.10.2.3.1

 

 

Note that the virtual server names use quotes. I beleive they are contained in a table. To snmget a specific virtual, you would need to use the OID number or escape the quotes.

 

 

snmpget -v 2c -c public localhost F5-BIGIP-LOCAL-MIB::ltmVirtualServStatClientPktsIn.\"mtest\"

 

F5-BIGIP-LOCAL-MIB::ltmVirtualServStatClientPktsIn."mtest" = Counter64: 694

 

 

To obtain the OID number, I use the -On switch:

 

 

snmpget -v 2c -On -c public localhost F5-BIGIP-LOCAL-MIB::ltmVirtualServStatClientPktsIn.\"mtest\"

 

.1.3.6.1.4.1.3375.2.2.10.2.3.1.6.5.109.116.101.115.116 = Counter64: 694

 

 

Thus a get with the OID number:

 

 

snmpget -v 2c -c public localhost .1.3.6.1.4.1.3375.2.2.10.2.3.1.6.5.109.116.101.115.116

 

 

Note that the OID numbers represent the ASCII equivelents. I think the 1st number in the tree ( 5 ) represents how many ASCII characters follow.

 

 

The manual gives a basic understanding:

 

 

Working with SNMP MIB files

 

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos_management_guide_10_1/tmos_snmp.html?sr=176942531041609

 

 

DevCentral has a ton of information on gathering statistics. For example, I searched on F5-BIGIP-LOCAL-MIB

 

http://devcentral.f5.com/Default.aspx?tabid=37&cx=015798286719081439686:g38hs-tdy64&cof=FORID:11&q=F5-BIGIP-LOCAL-MIB

 

 

Hope this helps.

Actually it looks like the F5 MIB files are not working. I'm getting a series of errors like this...

 

Cannot adopt OID in F5-BIGIP-SYSTEM-MIB: sysGlobalTcpStat ::= { sysGlobalStats 12 }

 

 

probably hundreds of them referencing all of the F5 MIB files.

 

some quick googling says that its likely the MIB files are in the wrong syntax

have you tried snmpwalk locally? did it work?

e.g.

[root@ve1023:Active] config  snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.3375.2.1.1.2
F5-BIGIP-SYSTEM-MIB::sysStatResetStats.0 = INTEGER: 0
F5-BIGIP-SYSTEM-MIB::sysStatClientPktsIn.0 = Counter64: 737174
F5-BIGIP-SYSTEM-MIB::sysStatClientBytesIn.0 = Counter64: 255313206
F5-BIGIP-SYSTEM-MIB::sysStatClientPktsOut.0 = Counter64: 944065
F5-BIGIP-SYSTEM-MIB::sysStatClientBytesOut.0 = Counter64: 1002808675
F5-BIGIP-SYSTEM-MIB::sysStatClientMaxConns.0 = Counter64: 3119
F5-BIGIP-SYSTEM-MIB::sysStatClientTotConns.0 = Counter64: 61502
F5-BIGIP-SYSTEM-MIB::sysStatClientCurConns.0 = Counter64: 1
F5-BIGIP-SYSTEM-MIB::sysStatServerPktsIn.0 = Counter64: 917075
...

probably hundreds of them referencing all of the F5 MIB files.

 

some quick googling says that its likely the MIB files are in the wrong syntaxjust a quick question. is MIB that has been imported to NMS really correct e.g. version?

I dont have direct access to the F5 as it is hosted. I am trying to setup MRTG to run from an Ubuntu install I have. MRTG is running for all my other devices, which is why I was trying to check SNMP directly.

 

I was able to

 

snmpwalk -v 2c -c public .1.3.6.1.4.1.3375.2.2.10.2.3.1 and it returned a bunch of the errors followed by a bunch of OID entries....

isn't .1.3.6.1.4.1.3375.2.2.10.2.3.1 in F5-BIGIP-LOCAL-MIB? why did you get F5-BIGIP-GLOBAL-MIB? where did you get MIB file?

I got the MIB file from the F5 itself

 

 

The version of the OS is 10.2.1

 

I should have caught that in the beginning. F5-BIGIP-GLOBAL-MIB refers to Global Traffic Manager. If you do not have this enabled, I doubt you would get valid data. F5-BIGIP-LOCAL-MIB is for LTM.

Forgive me, I'm not sure I understand what you mean?
