Apache Tomcat collector
Presents memory utilization of tomcat containers.
Charts:
Requests per second
- accesses
Volume in KB/s
- volume
Threads
- current
- busy
JVM Free Memory in MB
- jvm
Configuration
Edit the python.d/tomcat.conf
configuration file using edit-config
from the Netdata config
directory, which is typically at /etc/netdata
.
cd /etc/netdata # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/tomcat.conf
localhost:
name : 'local'
url : 'http://127.0.0.1:8080/manager/status?XML=true'
user : 'tomcat_username'
pass : 'secret_tomcat_password'
Without configuration, module attempts to connect to http://localhost:8080/manager/status?XML=true
, without any credentials.
So it will probably fail.
Troubleshooting
To troubleshoot issues with the tomcat
module, run the python.d.plugin
with the debug option enabled. The
output will give you the output of the data collection job or error messages on why the collector isn't working.
First, navigate to your plugins directory, usually they are located under /usr/libexec/netdata/plugins.d/
. If that's
not the case on your system, open netdata.conf
and look for the setting plugins directory
. Once you're in the
plugin's directory, switch to the netdata
user.
cd /usr/libexec/netdata/plugins.d/
sudo su -s /bin/bash netdata
Now you can manually run the tomcat
module in debug mode:
./python.d.plugin tomcat debug trace
