Hello,
I have installed nagios core with nagiosql and loaded few host and services where i have no issues on that part. However when I start increasing the host count, I see cgi/apache times out showing an error.
The gateway did not receive a timely response from the upstream server or application.
The host count is 5400 right now. I agree its huge and suspect there should be some tuning required to allow this much load but not sure where I should check. Any help would be helpful.
Here is the http error message I see whenever the frontend times out.
I also tried increasing the timeout to 90 seconds on httpd.conf but that doesnt help. Again this is the issue only when I add more host. I tried removing half of them and it started working normally.
Sorry for the delayed response. I have increased the timeout on http.conf and it started working. However, for some reason when i hit "Restart Nagios" from nagiosql, it saye "Nagios daemon is not running, cannot send restart command!" but looking through cli its running. Not sure why its showing like this.
