How to monitor load balancers A10 TH3040s

[echonoc]

Hi All, I need your help please. I need to monitor 4 loadbalancers, they are A10 TH3040s. We cannot install the nagios agent since they are appliances. We have enabled SNMP on them. We need to monitor PING, MEMORY and CPU.

The problem is that any of the wizards let us configure these checks. I tried to look for a pluging but I have not had any luck.

When I try to use the SNMP Linux Wizard I get the following error:

I do not know what to do to monitor this checks on these devices A10 TH3040s.

I hope you can help me on this

Thanks in advance

Hello @echonoc

Thanks for reaching out, let's have you run through the 'snmpwalk':

Code: Select all

snmpwalk -v 2c -c <rocommunity> xxx.xxx.xxx.xxx

or

Code: Select all

snmpwalk -v1 -c <rocommunity> xxx.xxx.xxx.xxx

Let us know how things look,

Hello @echonoc

Thanks for following up the snmpwalk info indicates that we are able to pull the snmp from the endpoint. Let's go ahead and manually configure the service checks via the command line to test and verify. Once functioning please go ahead and configure within the Core Configuration Manager.

To pull the <oid> list from the endpoint using this command:

Code: Select all

snmpwalk -v1 -On -c <yourcommunitystring> <yourhostaddresshere>

Also the option to convert as well:

Code: Select all

snmpttconvertmib --in=A10-AX-MIB.mib --out=A10.txtsnmpttconvertmib > A10list.txt

To manually configure the service checks for CPU, Memory, and sysuptime

Code: Select all

/usr/local/nagios/libexec/check_snmp -H <hostaddresshere> -C <communitykey> -o <oid> -w <warn_range> -c <crit_range>

If you find that 'sysuptime.0' is not listed in the mib(s), the option to use 'check_ping':

/usr/local/nagios/libexec/check_ping
Usage:
check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>%
[-p packets] [-t timeout] [-4|-6]

Hi @pbroste

Thank you for the help, I run this command:

snmpwalk -v1 -On -c <yourcommunitystring> <yourhostaddresshere>

and I get this info:

oid list.txt

How to know what is the OID that could provide me the information about memory usage.

Can you help me what is the next step?
thank you

Hello @echonoc

Thanks for following up, want to circle back and look into the 'Configuration Manager' to see if there are updates to install. It appears that snmpwalk is bringing up a full list of oid's.

You can update your wizard by going to:

Admin > Manage Config Wizards > Check for Updates > Install Updates

Let us know how things look,

Hi @pbroste,

I've tried to get the memory usage information using different wizards but without any luck.

1.-When I try to use the SNMP wizard I get the following and I do not know what OID should I use. If I do not select anything i get the message "You have no seleceted any OIDS"

Thunder Series Unified Application Service Gateway TH3040S, ACOS 5.2.1-p1,

Hello @echonoc

Thanks for following up, Attached are the three mibs that I could find on the A10 device. Let's have you copy those over to the device snmp mib directory and then run the 'snmpwalk' to list the mibs and oids.

Please send over the results,
Perry
