Hi Guys,
Here is a question I am hoping someone has either seen before or has a
suggestion for me.
For the first time since we put haproxy in months ago, the primary
haproxy we have did not respond in 10 seconds for the check on port
60000, which we have set as our health check port:
listen health_check 0.0.0.0:60000
mode health
When nagios checks port 60000 it looks for the OK in the response. Two
days ago, it did not get the OK in the max 10 second timeout. I am
running haproxy on a Dell R200, Dual Core 2.4GHz, with 2G of memory. I
have gone over the system logs and have not been able to find anything
wrong. I do have a script that is called via SNMP that calculates the
number of uniq IP's hitting the external IP on port 80 and at the time
it failed over there was only 2 IP's hitting it. Because this is for a
client who can not have any down time I allow a single time out,
checking the status every minute, before failing haproxy over to the
backup system. On the next check haproxy responded ok, but it had
already fallen over and no traffic was hitting it.
Has anyone else seen this happen where haproxy did not respond back or
it has taken longer than 10 seconds to respond? I would think it might
have been internet traffic, but the checks are from another system that
is on the same network over Gig ports.
Thanks for any suggestions or help.
Joe
