ITM Agent Insights: Monitoring logs with ITM: Log Monitoring Options
Monitoring the contents of log files is a common requirement for many environments, and IBM Tivoli Monitoring provides numerous solutions to assist customers with fulfilling this need. This post will provide a quick summary of available options for monitoring logs for different environments. Tivoli Monitoring provides many monitoring agents, and many application agents will gather data specific to logs for that application. Example, the UD agent can gather details from the db2diag.log for DB2 monitoring. Below are the "general"... [More]

ITM Agent Insights: Gathering CompositeData MBean attributes with custom JMX monitoring agent
IBM Tivoli Monitoring Agent Builder allows for the creation of custom monitoring agents using a JMX data source. JMX data sources gather attribute metrics based on MBean data. By default, custom agent attributes will not dig into a "CompositeData" MBean. This post will explain how to define custom agent attributes to gather the details for CompositeData MBeans by specifying the "Name" value for a sub-attribute to be passed to the "get" method. For general example of creating a JMX monitoring agent with Agent... [More]

ITM Agent Insights: Debugging Primary / Secondary Log Used Percent for ITCAM monitoring agent for DB2
ITM monitoring agent for DB2 databases - UD - can be used to monitor DB2 usage for transaction logs. The UD agent contains two attribute groups - Database01 (KUD_DB2_Database01) and Log (KUD_DB2_LOG) - either of which can be used to monitor the Log Used Percent. The attributes in these two attribute groups for log use percent are calculated the same way. Database01 (KUD_DB2_Database01) attributes Current Primary Log Used Percent The percentage of primary log space that is currently in use. Current Secondary Log Used Percent The percentage of...

ITM Agent Insights: Using "krarloff" utility to view binary short term historical data
IBM Tivoli Monitoring allows for collection of attribute data historically. Historical collections are defined through the Historical Collection Configuration editor in the TEP, and the short term historical (STH) files are stored at either the TEMS or the TEMA before the data is warehoused to the Tivoli Data Warehouse (TDW) database. STH data samples are written in binary to files named with the internal attribute group identifier, and a corresponding header file that has a .hdr extension. In order to review the actual historical sample data... [More]

ITM Agent Insights: UNIX OS monitoring agent on AIX and merged attributes from AIX Premium agent
The UNIX OS agent - UX - has incorporated numerous attributes that were previously provided by the AIX Premium agent - PX - that was part of the System P package. If experiencing problems with a "merged" metric, it is important to understand that different subsets of the "PX" metrics were incorporated at different levels of UNIX OS agent. Depending on which attribute group is not able to be collected, the issue may be due to the version of the UX component on the endpoint (or the level of UX agent application support). ... [More]

ITM Agent Insights: Security scans reporting "weak cyphers" or vulnerable ports against ITM / ITCAM agents.
In general with Tivoli Monitoring agents, problems related to "weak cyphers" or a specific "port" coming up in a security scan being cited as vulnerable are almost always related to Secure Socket Layer (SSL) communications (using IP.SPIPE or IP6.SPIPE communication method), or the IBM HTTP Server. Both of these rely on The IBM Global Security Kit (GSKIT) embedded package to provide the SSL protocols / ciphers for communication. The IP.SPIPE / IP6.SPIPE communication is a separate channel than the communication to the embedded... [More]

ITM Agent Insights: Installing ITCAM UD agent for DB2 monitoring installs back-level components
The DB2 monitoring agent by design installs both 32 and 64 bit UD agent components (necessitating both 32 and 64 bit shared libraries - AX, and 32 and 64 bit JRE and GSKIT) because the bitness of the UD monitoring agent must match the bitness of the DB2 installation. Since DB2 allows for both 32 and 64 bit databases, the monitoring agent must provide 32 and 64 bit UD agents. The ITCAM for DB2 installation image packages back-level Common Installer components, which can result in older levels of AX / JR / GS components being installed for... [More]

Can the LO agent be used to monitor a "circular" or "rolling" log file? Yes. But there are limitations. Is it recommended? No. It is up to the user to determine if the need to montor a circular log can be accomplished with the LO agent given its design limitations. The LO agent is primarily intended to read data that is appended to a monitored log, and works by periodically polling the identified file and making checks to determine if there is "new" data to process, and then processes those "new" entries.

ITM Agent Insights: Agent Builder custom agents relying on "Ping" data source must be run as "root" on UNIX / Linux.
Gathering PING metrics requires "root" authority due to the underlying ICMP protocol. Opening a raw socket to send / receive data on when issuing a "ping" request requires "root" authority. This applies even when running "ping" command manually. This is why the "ping" command has "setuid" bit set so that when it is issued by a non-root user, the setuid bit being set runs the command as if it had been initiated by "root": Example: $ ls -l /bin/ping -rw s r-xr-x 1 root root 38264 Nov 13 ...
