Checking System Health and Performance

The CloudView Monitoring Console is based on JRDS (http://jrds.fr/). It provides detailed system-wide performance analysis, both historic and real-time for:

• EXALEAD services (search and indexing statistics, data structure size, etc.)
• System statistics (CPU load, disk and network activity, memory usage, etc.)
• EXALEAD process health (CPU usage, memory usage, IO activity, etc.)

The Monitoring Console is available at: http://<HOSTNAME>:<BASEPORT+1>/perf-ui.

• Select the:
  • All hosts tab to display performances by host.
  • All views tab to display performances by service.
• For each host, the tree list displays the following node:
  • Disk: disk I/O usage
  • Services:
    • EXALEAD: performance of internal services
    • JVM: performance of CloudView processes
  • System: performance of the host machine

• To filter the graph views by date, specify a Time scale.
• To filter the values of the graph ordinate (vertical axis), clear Auto and specify the min and max values to display.

By default, CloudView logs the details of search queries in <INSTALLDIR>\<OS>\cv\data\run\searchserver-ss0\search-reporting\search.csv.

Example:

#timestamp;apiclient_ip;query_logic;query_target;query_querystring;query_language;query_start;

You can build your own monitoring based on .RRD files located in <INSTALLDIR>\<OS>\cv\data\perfmonitoring\probe\<HOSTNAME>.

Example: if you need to check CPU stats, use the following file: <INSTALLDIR>\<OS>\cv\data\perfmonitoring\probe\<HOSTNAME>\cpustats.rrd
