NetXMS Support Forum

Dear all,

I would like to monitor windows server 2003 I/O disk performance such as average disk queue and Disk I/O by using SNMP.

I did try to import WINDOWS-NT-PERFORMANCE.MIB to NetXMS and recompile MIB database.
http://www.oidview.com/mibs/311/WINDOWS-NT-PERFORMANCE.html

pdiskAvgDiskQueueLength -> 1.3.6.1.4.1.311.1.1.3.1.1.4.1.5
However, it doesn't work.

Is there any way to check I/O activity without installation agent on monitored host?

Regards,
Kelvin Sin.

Log file is named as below pattern
AMS3AutoDealerLog00Thu06Jan2010.AMS3
AMS3AutoDealerLog01Thu06Jan2010.AMS3
..
..
..
..
AMS3AutoDealerLog23Thu06Jan2010.AMS3

Pattern is
AMSAutoDealerLog<00-23><MON-FRI)<DDMMMYYYY>.AMS

log file will be generated every hour.

Dear Victor

Thank you for your reply. Where do i insert external parameter in NetXMS? Do i put it in DCI?
I would be appreicated if you could instruct more detail information. Thank you.

P.S. I am running windows server 2003 OS in server side.

My monitored application will generate new log file every hour.

Latest log file is heavily accessed and written by application. On average, log file size is 1.5M every hour.  All contenet is in text format.

I am afraid that it affects application performance. Therefore, I just monitor pervious version log file which is generated last hour.

This is why I look repeatedly for old records in a file.

Question 1: Is there any idea to monitor old records in a file?
Question 2: Is there any performance issue about monitor heavy read+write operation log file by logwatch? Is there any limitation?

Dear Victor

Detect change in that page doesn't help for me. It is because i need to detect portion of change in web page. Is there any idea about writing external script, please? Please advice.

Hi Victor,

First of all, thank you for your help.

Regardinging question 1, I want to search some OLD string inside file. this is static file instead of log file.
I think i can't use logwatch subagent method to check it. It is because string can only be searched when NEW line is added. Am i misunderstanding usage of logwatch subagent.

Dear all,

I solve this problem by using WMI query
WMI.Query(root\cimv2,select * from Win32_PerfRawData_PerfOS_Memory,PoolNonpagedBytes)

As title.

There are some two requreiments for monitoring system

1. Search specific keyword of file(c:\test.txt) in local drive of agent every 1 hour.

2. Search existence running process for example notepad.exe in windows platform of agent every 1 hour

May i know how to configure in NetXMS? Thank in advance.

Dear all,

In monitored web page, it contains value in <lastdataintime> field as shown below.


<lastdataintime>16:21:17 18/12/2010</lastdataintime>

My task is to monitor if there is any change for this value -16:21:17 18/12/2010

Email alert will be sent if the value of XML tag "<lastdataintime>" is unchanged every 3 minutes.

Is it possible to monitor change of web page content?

I would be appreicate if you have any hints about configuration.

Kelvin Sin
