server uptime

[popeye]

Hi not sure if anyone can help but i keep getting alerts from Pingdom saying my server had been down,
but when i check its still online and just wanted to know if there was any logs on the server that would tell if it had or not ? or what errors if it had.

Hello

Is it stating a specific service was down, or the server in general? You can check the system uptime via the following command:

uptime

Thank you.

You can check uptime of the server itself with 'uptime' at an ssh prompt, that will show time since the last reboot.

also, the command:

/etc/init.d/httpd status

will show server uptime for apache itself. This should get you a good start.

Hello,

You might also check if pingdom is checking a specific port or if they are using ICMP packets (ping) to check and that you have not recently blocked that via your firewall.

Got this result below, Pingdom checks http

21:21:56 up 4 days, 19:03, 1 user, load average: 0.23, 0.22, 0.18

root@srv1 [~]# /etc/init.d/httpd status
Not Acceptable

/whm-server-status could not be found on this server.

Additionally, a 404 Not Found error was encountered while trying to use
an ErrorDocument to handle the request.

Are you using a third-party web server such as LiteSpeed or Nginx in place of Apache? Do you get the same output when running "/usr/sbin/httpd status"?

Thank you.

 

[popeye]

No its running Apache have got Litespeed installed but been disabled for a long time now.

And yes get the same error with /usr/sbin/httpd status

You'd better set two or more monitoring sensors with pingdom on different things like ICMP, HTTP, etc - if all of them are showing to be down at once it could be your server' network issues that you need to check with your datacenter about that.

Also if you've firewall don't forget to allow all pingdom IPs so that they won't get blocked.

Do you know where i can get the list of ips from ?
