Logfile Monitoring Monitor  

Use

You can use this monitor to search any log files for the occurrence of text patterns of your choice. This is done using a CCMS agent that takes the required information about which text pattern it should search for in which files from one or more configuration files.

Integration

As the search for the text patterns is performed by a CCMS agent, this agent must be installed and active (see Installing and Registering the CCMS Agents) on the host that contains the desired log file (or at least on a host from which it can access the desired file).

Prerequisites

You must have created the configuration files that contain the information about the log files to be monitored and the text patterns for which the agent is to search (see Monitoring Log Files with CCMS Agents).

Features

The monitor creates a subtree for every monitored file. The name of the subtree consists of a prefix and the name of the file. You can use this prefix, which you set in the configuration file for the monitoring (see Structure of the Log File Template of the Log File Agent), to differentiate between different files with the same name that you want to monitor. Each subtree consists, at most, of the following monitoring tree elements (MTEs):

MTE	Description
Complete Name	Complete name including file path of the monitored log file from the point of view of the monitoring CCMS agent You can also display the content of the monitored files in the Alert Monitor. To do this, double click the Complete Name attribute in which the name of the monitored file is displayed.
Info[<Name>]	If you are searching for search patterns with no alert value, the system displays the line that contains the search pattern APPL_INFO_<n> in the text attribute Info[<APPL_INFO_MTE_NAME_<n>>] (see Examples of Logfile Templates).
Monitored Patterns	Search pattern with alert value (see Examples of Logfile Templates); you can monitor a file for multiple search patterns (the system displays these in the monitor separated by |)
Lines found for pattern	Lines of the log file that match the search pattern
Data Collection Check	Time of the last check of the log file; this status attribute is always colored green.
File Time Stamp	Time of the last change of the monitored log attribute; this attribute is only created if you specify the parameter MONITOR_LAST_FILE_MODIF=1 in the log file template
New Lines in Log File	Growth of the monitored log file in lines per minute; this attribute is created only if you specify the parameter SHOWNEWLINES=1 in the log file template
Log File Size	Size of the log file; this attribute is created only if you specify the parameter MONITOR_FILESIZE_KB ³0 in the log file template (if MONITOR_FILESIZE_KB>0, you also assign an alert threshold value to the attribute by setting)
