Hi All,
This is from the server's log
ERROR [tomcat-http--29] [org.hyperic.lather.server.LatherServlet@219] Invalid Lather request made from xxx.xxx.xxx.xxx
This is from the agent's log
DEBUG [PluginStatusSender] [AgentCallbackClient@190] IO error: Connection failure: HTTP/1.1 503 Invalid Lather request made from xxx.xxx.xxx.xxx
WARN [PluginStatusSender] [AgentDaemon@776] could not send plugin status to server, will retry: org.hyperic.hq.bizapp.client.AgentCallbackClientException: IO error: Connection failure: HTTP/1.1 503 Invalid Lather request made from xxx.xxx.xxx.xxx
Anybody encountered the same problem??
I'm using version 5.8.0 for both the agent and the server
Both are running on Linux CentOS release 6.5
Tried using with and without SSL, but still encounter the same problem.
Been searching through the forum but none of the solution works for me.
Thanks for reading this.
Finally able to solve this problem.
Just in case others may need to know this in future.
The MTU of the HQ server and the agents are set to 2000.
This may be too big which resulted in the loss of packets being transmitted from the agents to the HQ server.
Due to the loss of packet, it may become an invalid requests. (My guess)
To set the eth interface to a lower MTU
use the following command
ip link set eth0 mtu 1500
The above solve my problem. Hope this may come in handy for others
Does this error happens all the time? metrics don't arrive to server? inventory?
Do you have more agents which work? if yes, are they on the same O/S?
This is a fresh installation which i just started trying.
None of the agents work.
The HQ server and the agents are running on different VMs
telnet from agent to server works for port 7443 and 7080
All servers are running on Linux CentOS release 6.5
I just installed the agent on the server itself and everything is working fine.
Still unable to figure out why I'm getting the error from other agents on other nodes.
Any help is appreciated!!

Thanks for sharing your solution with us. We have never seen that in our environments but it is good to know that it is a potential problem that you can face using the agent --> server communication channel.
