Tivoli Logfile Adapter HealthChecker

The IBM Tivoli Enterprise Console (TEC) Adapter Health Checker comprises Tivoli Distributed Monitoring probes included in a monitor collection developped in standard MCSL (Monitor Collection Specification Language) format. The aim of the Windows and Unix probes is to ensure that TEC Adapters are correctly monitored and application logs and are not in a stalled state. The present checker is more efficient than any basic monitoring system that would only check the presence of a process. The checker verifies that the TEC adapter is still able to process the messages arriving in the monitored log file. The principle of the TEC Adapter Health Checker is to write into the monitored log file, a dummy message that does not match any defined format in the TEC Adapter configuration. If the TEC Adapter is alive, this unmatched message is written in the Unmatchlog and the program checks that the Unmatchlog has been updated. This mechanism allows the checking of the adapter activity while not using any network bandwidth. This is a good intermediate solution between a heartbeat mechanism using TEC rules and a simple adapter process status check.

    The windows and Unix probes are based on the same logic. First, they generate in the input pipe of the adapter a log entry (or line) that does not match any format entry in the format file of the adapter (also called .FMT file). Second, they check whether ot not the entry is correctly parsed and logged in the unmatch log by the adapter (the UnmatchLog parameter of the TEC Adapter must be configured). The TEC Adapter Health checker supports:

Several Logfile Adapters on AIX, by using a configuration file describing the adapters that must be monitored. Several Logfile Adapters on AIX, without the need of a configuration file, provided that all adapters are installed under the same main directory. The Windows NT Event Adapter.
