Use ganglia to monitor storm Clusters
Recently, some tasks in the storm cluster cannot be started and executed properly due to unknown reasons (several projects are reused ), so I want to get a monitoring system to monitor the status of the storm cluster and handle the corresponding alarms. Finally, ganglia, an open-source monitoring platform, is selected. Ganglia can use jmxtrans to monitor storm. jmxtrans serves as a communication bridge between ganglia and storm.
1. Download and install jmxtrans
You can use wget to download
Wget https://cloud.github.com/downloads/jmxtrans/jmxtrans/jmxtrans-20121016.145842.6a28c97fbb-0.noarch.rpm
Sudo rpm-I jmxtrans-20121016.145842.6a28c97fbb-0.noarch.rpm
After installation, the jmxtrans directory is in the/usr/share/jmxtrans directory, the configuration file is in the/etc/sysconfig/jmxtrans directory, and the json script for monitoring storm is placed in the/var/lib/jmxtrans directory.
2. Modify storm Configuration
Add the following two parameters to storm. yaml:
Supervisor. childopts: "-verbose: gc-XX: + PrintGCTimeStamps-XX: + PrintGCDetails-Dcom. sun. management. jmxremote-Dcom. sun. management. jmxremote. ssl = false-Dcom. sun. management. jmxremote. authenticate = false-Dcom. sun. management. jmxremote. port = 12346"
Nimbus. childopts: "-verbose: gc-XX: + PrintGCTimeStamps-XX: + PrintGCDetails-Dcom. sun. management. jmxremote-Dcom. sun. management. jmxremote. ssl = false-Dcom. sun. management. jmxremote. authenticate = false-Dcom. sun. management. jmxremote. port = 12345"
The port numbers 12345 and 12346 can be set at will, preferably useless or infrequently used port numbers.
3. Write monitoring scripts
Supervisor. json

Port 12345 is the port of the jmx service, which is set in storm. yaml;
IP_OF_NIMBUS_MACHINE is the IP address of the nimbus node.
IP_OF_GANGLIA_GMOND_SERVER is the IP address of the server where the ganglia gmond service is located.
4. Copy the nimbus. json and supervisor. json scripts to the/var/lib/jmxtrans directory.
5. Start the jmxtrans Service
Cd/usr/share/jmxtrans
Sudo./jmxtrans strart
6. Now you can view the running status of the storm cluster on the wen service of ganglia.
