#HOW TO INSTALL GANGLIA ON WINDOWS 7 HOW TO#
Now we see how to install ganglia and configure it: In the above diagram the gmond collect data at each node and send to gmetad and use can monitor it with web-interface. So from above component we can draw the below architecture Ganglia web interface: Its provide a web interface which aggregate all node data and represent in metrics form and we can monitor specific node of cluster.gmetad: gmetad is a metadata deamon to collect data from the monitoring deamons and store it into RRD(round robin database).gmond: gmond is monitoring deamon which collect data from each node in the cluster and send it to specific host.Ganglia have 3 main components as follows: Now we see how Ganglia works and its internal architecture. So we now we got the answer that ganglia use for Advance Monitoring of any cluster. And with the help of spark default monitoring we cant monitor whole cluster hardware health and all matrices for each parameter like cpu usage, ip addresses, memory etc. I know you all have question that we already have a Application UI ( and Cluster UI ( then why we need ganglia? So answer is, Spark cluster UI and application UI dont provide us all information related to our cluster like Network I/O and health of every node. Ganglia is cluster monitoring tool to monitor the health of distributed cluster of spark and hadoop.
