List of PMI metrics for Sametime Gateway servers
In addition to the general metrics collected for IBM® WebSphere® Application Server, the PMI tool collects the following metrics for IBM Sametime® Gateway application servers.
Each metric (in the Metric Name column) can have multiple instances, with each instance measuring a different community or time resolution, described in the columns that follow.
Note: You must
have metrics collection enabled (to either "Server Health" or "Problem
Determination" level) for Sametime Gateway before
you can view these statistics.
When reviewing the table, use the following column descriptions to help you understand the value of each metric:
- By Community slicing
- Specifies how many different instances of this metric per community we will have:
- Global scope: the metric is gathered across all communities.
- Sliced by source community: that there would be multiple metric instances.
Each instance measuring events generated by a specific source community. For a subscription event, the source community is the subscriber's community. For a chat invitation event, the source community is the chat initiator community. The total number of by community metric instances will be multiplied by the number of time-resolution metric instances (see next row).
- By Time-resolution slicing
- Specifies how many different instances of this metric we will have. For example: Since startup AND for the last 60 seconds means that there will be two metric instances, one counting since measurements were started (server started, or PMI enabled), and another that keeps measurement for the last full 60-second cycle.
- Statistic types
- Statistic types are taken from the PMI Data statistic types table.
- Set types
- Denotes whether this metric is included in the Server Health set or only in the Problem Determination set.

| MaxAllowedPresenceSessions | The maximum number of allowed presence sessions | Global scope AND sliced by community (a limit on the number of sessions involving this community) | Constant | Constant | Server Health |
| IMSessionsCount | The current number of active IM sessions | Global scope AND Sliced by target community | All time peak and current value | RangeStatistic: peak and current value | Server Health |
| MaxAllowedImSessions | The maximum number of allowed IM chat sessions | Global scope AND Sliced by community (a limit on the number of sessions involving this community) | Constant | Constant | Server Health |
| TranxTotalByStartupCount TranxTotalByPeriodCount | The total number of processed transactions | Global scope AND Sliced by source community | Since startup AND For the last period of 60 seconds | CountStatistic | Server Health |
| TranxFailedByStartupCount, TranxFailedByPeriodCount | Number of processed transactions that have failed (exceptions) | Global scope AND Sliced by source community | Since startup AND For the last period of 60 seconds (configurable) | CountStatistic | Server Health |
