Sync Missed

[sigtom]

Hey,

CentOS 32 Bit 5.6
Manual Install
No special configs

Im trying to get this up and running, and it so far, whenever I add 2 switches in particular, I get the issue where applying config just sits there, and times out giving me .... I kill and restart nagios, and then check the services for the switches, and any device added after it (linux server in the most recent case), and they all say Sync Missed. I go to Write Config Files, hit all the buttons there, no errors. I go to Apply Configuration, and have no issues there. Ive deleted all services and hosts for the 2 switches and linux server. Any config I add after that, excluding the 2 switches and linux server from before, also say Sync Missed. When going thru the Config Wizard the switches are polled correctly, showing port name and speed correctly. I can just never get the services going to get them to report to the XI server. Heres most recent config snapshot:

Any more info I can add?

Switches are Foundry FESX. Linux server is CentOS VMware Image. I have wiped and reloaded once already, the first time the linux server did report fine. The 2 switches mentioned gave me the sync missed issue in the first install, hence the reload.

Id appreciate any help I can get. Need to get a demo of our network going for the BTP. Thanks!

Take a look at these solutions first and see if these might be the issue.

Also, make sure your server's time is up to date.

Code: Select all

yum install ntp
ntpdate pool.ntp.org

If those don't resolve the issue then it might be related to the switches, and we'll have to do some more digging in that direction.

Are you able to get the files to sync up when you use the "Write Config Tool"?

Hello,

Thank you very much. Increasing the mem limit in PHP is what fixed it for me. Once I applied the config after increasing the mem limits and max execution time, everything showed as sync. On to add more devices!

Hello,

I ran into this "Sync Missed" issue, with the following setup.

NagiosXI 2012R2.3
CentOS 6.4 - 64 bit
164 hosts / 1697 services

Increasing the values for 'memory_limit' and 'max_execution_time' in the '/etc/php.ini' file ,followed by a restart of the web server, solved the problem.
