webserver agent is not connecting.
Hi,
We have deployed dynatrace agent on OHS web server. It was working fine. But today after I restarted the OHS service thewebserver agent is not connecting. It is frequently showing popup for "Agent connection lost".
In the Agent Overview dashboard it is showing agent in disconnected state.
Please suggest what could be the cause. It is critical as data collection is stopped.
Regards,
Jaydatt
Have a look at the Agent Logs. You can find them on your application servers in case your agents are not connected - otherwise you could retrieve them through the System Information Dashlet.
Most likely there is a network connectivity problem with your Agents - meaning - that the AGents cannot connect to the Collector. Have you changed anything on the network? any firewalls?
Also have a look at the Collector. Make sure the Collector is up and running before you start your application.

HI Andreas,
there is no connectivity problem and we are able to telnet collector from app server where my agent is install.
and my collector is also working fine.
Please suggest.
Jaydatt.
please find the logs...
Based on the logs it seems that there is a problem with one of the connections between your web server agent and the collector. It might not be network related as the initial connection works.
All I can recommend right now is to
a) try to reboot your server once again
b) open a support ticket in case this reboot doesnt help

adding to this 1 more big problem that I am facing is that now I am not getting pure path data and BTM data for past.
Yes - thats because your agent was never connected after your restart. This can be seen in your log files as the Agent has tried reconnecting all the time but didnt succeed
So - if this is urgent please go ahead and contact our support team if you cant solve this problem with another restart
Keep us posted with your outcome on this.

We were able to see all the data till 7 pm but after restart of server now I m unable to see any kind of past data (not even 72hr data)
Please suggest.

If you dont see historical data you probably lost connection to your Performance Warehouse
I recommend you contacting our Support Team. It seems there might be more going on in your environment. It probably is a simple fix but you will get better help when contact our Support Team.
All the best - and - keep us posted

Hi
Check out the Troubleshooting Guide on the Knowledge Base - TroubleShooting Guide and the attached Troubleshooting PowerPoint I used at a recent dynaLearn Webinar
Here are some quick things to check
a) Are all your Collectors Connected (Server Settings)
b) Are all your Agents Connected (Agent Overview)
c) Is your dynaTrace Installation Healthy: Deployment Dashboards
d) Do you see any errors in the Agent, Collector or Server Logs
I hope this helps - and - I am sure the support team will solve your problem in case these steps dont help
