Hi Appdynamics Gurus,
I am new here and using a trial license trying Appdynamics.
I have installed machine agent via rpm way on my 3 linux servers: 2 of them had Javahardwaremonitor enabled and the rest had Hardwaremonitor enabled. All of the 3 machine agents had been started successfully from log files.
However, there is nothing displayed in the controller dashboard:
From the log files, all of the agents are at:
INFO ServersDataCollector - Started servers data collector - DataCollectorConfig(samplingInterval=30001, componentNames=[remote.volumes, partitions]) INFO ServersDataCollector - Started servers data collector - DataCollectorConfig(samplingInterval=3000, componentNames=[memory, partitions, volumes, cpus]).
May I know what I should do to have the data displayed?
Btw, the machine agent I am using is appdynamics-machine-agent-188.8.131.5288.x86_64.rpm.
Thanks for asking your question on the community. There seem to be a few other similar questions around this topic.
Here is a recent one:
Here is a TKB: Why is the Machine Agent not reporting properly?
If those don't help, perform a search across the community in the forums and the Knowledge Base.
Let me know if you are able to find anything!

Thanks for your reply.
The KB you pasted I have checked already and went through the workaround in my env, but still no luck. Regarding the checkpoints in the other link, here are mine:
1. Are you using an On-Premise Controller or a SaaS Controller?
- SaaS Controller.
2. Have you validated that the connection is open from the Server where you have installed the machine agent to the Controller? Using Telnet/Curl.
- I tried curl command in my env:
[root@centos8 ~]# curl lee202111022159422.saas.appdynamics.com https://lee202111022159422.saas.appdynamics.com/ [root@centos8 ~]# curl lee202111022159422.saas.appdynamics.com/controller https://lee202111022159422.saas.appdynamics.com/controller
3. Have you configured the machine agent controller-info.xml file with the variables e.g host, port, ssl, access key etc?
- Here is my configuration:
<?xml version="1.0" encoding="UTF-8"?> <controller-info> <controller-host>[saas-controller-host-value]</controller-host> <controller-port>443</controller-port> <controller-ssl-enabled>true</controller-ssl-enabled> <enable-orchestration>false</enable-orchestration> <unique-host-id>homelab</unique-host-id> <account-access-key>[access-key-value]</account-access-key> <account-name>[account-name-value]</account-name> <sim-enabled>false</sim-enabled> <machine-path></machine-path> </controller-info>
4. What does the logs indicate, it would tell you either it can't connect etc.
- The latest machine agent log:
INFO ServersDataCollector - Started servers data collector - DataCollectorConfig(samplingInterval=30000, componentNames=[availability, load, monitored.process.classes, networks, operating.system]). Started servers data collector - DataCollectorConfig(samplingInterval=30001, componentNames=[remote.volumes, partitions]). INFO ServersDataCollector - Started servers data collector - DataCollectorConfig(samplingInterval=3000, componentNames=[volumes, memory, partitions, cpus]). INFO SystemAgent - Full certificate chain validation performed using default certificate file
I am using a trial license, the machine agents installed on my 3 servers were running the whole night but got nothing from the controller though they were recognized already:

Unfortunately, Server Visibility is not part of that as I tried as well, log is like:
INFO SecondStageSystem - Starting main system with features Features(features=[dmm], reason=Features.Reason(message=Unsuccessful leasing a Server Monitoring license, code=License Lease Failed))
And from the controller console, there will be a notification:
Till now, I am wondering what this pro trial license could do...
Thanks for your kind reply.
I bet I did not miss any other error info in the log files and I am wondering if you are available to join in a zoom session so that I could share with you the configuraiton online, that would be more straight forward.
Please let me know your opinion.
