Handling Procedure

Check the time spent on a real-time path query request on the GraphServer node.

  1. On the FusionInsight Manager homepage, choose O&M > Alarm > Threshold Configuration > Name of desired the cluster > GraphBase to view the threshold of Response Time for a Path Query on GraphServer.
  2. On FusionInsight Manager, choose O&M > Alarm > Alarms and select the alarm whose ID is 43614. Check the role name and the IP address of the host where the alarm is generated in Location.
  3. On the FusionInsight Manager homepage, choose Cluster > Name of the desired cluster > Service > GraphBase > Instance. Click the GraphServer where the alarm is reported. On the dashboard page that is displayed, expand the drop-down list box in the upper right corner of the graph area, choose Customize > Response Time for a Path Query on GraphServer, and click OK to check whether the query time of the current path exceeds the threshold.

    • If yes, go to 4.
    • If no, go to 6.

  4. On the FusionInsight Manager homepage, choose O&M > Alarm > Threshold Configuration > Name of desired cluster > GraphBase to update the threshold of Response Time for a Path Query on GraphServer.
