Activity Monitor of a Metaspace

The activity monitor can be used to see how some operations were performing over a point in time.

The activity monitor provides a set of charts capturing the historical statistics of the activities on a space operation that are performed by members of a metaspace. The statistics is gathered continuously over time and aggregated on the server.

The following set of activities can be monitored:
  • Space Put and Take Operations
  • Space Get and Query Operations
  • Average Get Throughput
  • Average Put Throughput
  • Average Member Get Latency
  • Average Member Put Latency

The recent statistics is always displayed on the rightmost pane for each data series. Data is captured periodically in regular intervals on the ASMM server. Each graph is a view that continuously rolls to present near real-time data. You are presented with a graphical view of the statistics on the browser based on the selected category of activities. Each presented graph contains a fixed number of data points based on the selected time periods.

You can view the historical data of the operations mentioned in the bulleted list over the following periods in time:
  • last 10 minutes
  • last 1 hour
  • last 4 hours
  • last day
For example, you can see the Space Put and Take Operations of the last 1 hour.
  • Space Put and Take Operations
    Space Put and Take Operations takes into account all the updates for all spaces that are performed by all members connected to the metaspace.
  • Space Get and Query Operations
    Space Get and Query Operations takes into account all the queries made to a metaspace.
  • Average Put Throughput
    The Average Put Throughput is used to display the average Put throughput over a point in time.
  • Average Get Throughput
    The Average Get Throughput is used to display the average Get throughput over a point in time for all spaces and all members.
  • Average Member Put Latency
    Average Member Put Latency is used to display the average Put latency for a member. Latency refers to the time elapsed to complete a Put operation performed by a space member.
  • Average Member Get Latency
    Average Member Get Latency is used to display the average Get latency for a member. Latency refers to the time elapsed to complete a Get operation performed by a space member.
