Hello,

I have a DNS and found Alerts on the log that says:

 

  gtm 2022-12-14 07:45:49.000 +01:00  Alert 011a2003: gtm1.hamza.ma gtmd[15209] SNMP_TRAP: Link /Common/ISP1 (ip=213.218.10.192) state change green --> yellow (Link limit(s) exceeded on GTM) 
  gtm 2022-12-14 07:46:19.000 +01:00  Alert

 011a2002: gtm1.hamza.ma gtmd[15209] SNMP_TRAP: Link /Common/ISP1 (ip=213.218.10.192) state change yellow --> green

This happens every minute.

Could anyone please clarify what this means?

Regards,

Hi Hamza,

I suspect you have a link (ISP1) configured in the DNS module (DNS - GSLB - Links) that is configured with very small limits. Probably every minute when some synchronization or other job happens, that limit is reached and temporarily marks the link as Yellow. 

I would suggest looking at the utilization of the datacenter links and see if either the links are overloaded, or the limits are too low. 

Hope this helps. 

Hi @AlexBCT,

Thank you.

Could you explain what you meant by limit?

Normely, if limit of a link means the bandwidth, my link is good.

However, please how can i change this limit of the link ?

Regards.
