hdb.exe high CPU Usage

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

The UIM robot's hdb.exe CPU usage is unexpectedly high (> 50% )

Environment

UIM 8.xrobot 7.xlogmon

Cause

Usually we see this when there is a logmon probe on the affected robot that is monitoring a very busy log file or a very large number of log files or with ntevl doing the same.

Resolution

- Check if there is any logmon probe on the affected robot.

- If so, deactivate it. If after deactivating the logmon probe the CPU usage of the hdb.exe drops down to normal, you will know that is logmon what is causing this issue. 

- Drill down into the different logmon profiles and try to locate which profile/s is overloading the robot. 

- Locate any profile where logmon is scanning a very large number of log files (Eg. using wildcards *.log) and/or with a polling period too short (5 sec).

 

The same is applicable to ntevl
