Setting threshold warnings for monitoring server load

Set up a warning so that a message appears when the maximum number of subscriptions or instant messaging sessions is approached. This is useful for monitoring server load due to instant messaging and subscriptions.

About this task

Create custom properties that define two threshold values: one for instant messaging sessions, and one for subscriptions. Whenever either of these values is reached, the warning message will appear in the log.

Expected state:
  • Single server: the Sametime® Gateway Server server is started.
  • Cluster: the deployment manager is started, and the node agent and the Sametime Gateway Server server are started on at least one node.

Procedure

  1. In the Integrated Solutions Console, open the Custom properties page for the server.
    • On a single server: Click Servers > Server Types > WebSphere application servers > server_name > Server Infrastructure > Administration > Custom Properties.
    • On a clustered server: Click System administration > Cell > Custom Properties
  2. Click New and enter the following settings (listed in Table 1) for the subscriptions threshold warning.
    Table 1. Custom property fields for the subscriptions threshold warning
    Field Recommended value
    Name com.ibm.sametime.gateway.max.subscriptions.warning.threshold
    Value A number representing the threshold value (the maximum number of subscriptions allowed before the warning message is generated in the log).
    Description Threshold warning message for maximum subscriptions
  3. Click OK to save the new custom property.
  4. Click New again, and enter the following settings (listed in Table 2) for the instant messaging threshold warning.
    Table 2. Custom property fields for the instant messaging threshold warning
    Field Recommended value
    Name com.ibm.sametime.gateway.max.im.warning.threshold
    Value A number representing the threshold value (the maximum number of instant messages allowed before the warning message is generated in the log).
    Description Threshold warning message for maximum instant messaging sessions.
  5. Click OK to save this new custom property.
  6. Restart the Sametime Gateway Server server; if you have a cluster of Sametime Gateway Server servers, restart the cluster.
