The OpsMgr UNIX/Linux monitoring team at Microsoft is currently investigating an issue that results in heartbeat failures on Operations Manager UNIX/Linux agents after the security update KB2585542 is applied to a Management Server or Gateway. This update fixes a vulnerability in SSL/TLS1.0, but appears to cause WS-Management connections to UNIX/Linux agents to fail. The vulnerability is described [...]

Introduction In Part III of this series, I walked through creation of data sources, a discovery, and a rule for discovering dynamically-named log files and implementing an alert-generating rule for log file monitoring. In this post, I will continue to expand this Management Pack to implement performance collection rules, using WSMan Invoke methods to collect [...]

Introduction In Part II of this series, I walked through creation of data sources, a discovery, a monitor type, and a monitor for customized ”Process Count” monitoring for discovered instances of a ”Service” class. In this post, I will continue to build on this example MP to implement dynamic log file discovery and monitoring. Dynamic Log File Discovery and Monitoring Log file [...]

Introduction In Part I of this series, I walked through creation of a custom Management Pack for monitoring an application hosted on a UNIX or Linux server, as well as the creation of some base data sources and application discovery. In this post, I will build on this MP to implement custom process monitoring – [...]

Introduction The OpsMgr UNIX and Linux monitoring implementation can be extended through MP authoring to implement robust system and application monitoring for UNIX/Linux servers. The most direct mechanism of extension comes in the form of the script provider, accessed with WSMan Invoke modules. The WSMan Invoke modules support three methods of invoking actions: ExecuteCommand – [...]

While this blog has been a bit quiet lately, it has not been for lack of efforts. In the next two weeks, a minor update to the xSNMP suite should be ready with a few bug-fixes and feature improvements. This update will also include three new management packs: xSNMP for Juniper Networks xSNMP for SonicWALL [...]

I was recently asked a question on this topic, and I thought it was worth sharing. In this post, I described discovering Oracle processes with enumerations of instances of the SCX_UnixProcess class that are filtered on the values of the “Parameters” property. The question I was asked involved a problem with a similar discovery process [...]

While the vast majority of the rules and monitors in the Oracle SCX management pack (part 1, part 2, part 3) that I am working on involve the basic form of a SQL query data source (see part 2) that queries a specific parameter value to evaluate the result, there are two areas of monitoring that required discovery [...]

Continuing on with the development of a management pack for monitoring Oracle database servers on a UNIX/Linux platform (part 1, part 2), I will describe in this post some of the characteristics and methodology of the class structure and object discoveries. Class Structure To start the class structure, I defined a few arbitrary abstract classes [...]

In the first of my posts regarding development of an UNIX/Linux Cross-Platform management pack for monitoring of Oracle, I described the creation of two custom probe action modules for WSMan Invoke Action and Shell Command Execution operations. In this post, I will describe the creation of a third custom Probe Action for executing SQL queries [...]
