However, telnet is not installed on Nagios. Perhaps, I should be able to telnet.
Pls. let me know how should I get rid of this. I have to do this for more than 200 Windows servers.
My concern is, If I am monitoring Using SNMP, it shows correct Memory Utilization.
So is it Good Idea to monitor servers using SNMP.
Plugins return different info, other words, the format could be different. If you like better the SNMP check format, you should use this one, instead of check_nrpe.
Be sure to check out our Knowledgebase for helpful articles and solutions!
It was just an example.
There should be solution of it. Because I am able to detect used memory, only I should see physical memory. thats it.
Do i need to do some changes in core config.
Also let me know if I would opt for SNMP monitoring, there are more than 200 windows server. On which I have to do the changes.
So is there any automation can I use , without downtime.
How have you defined the command on your nagios server when you run it? The plugin will only return the metrics it was written to return, this by no means is a limit however because you can monitor metrics such as these with more detail or in different fashions with SNMP, custom plugins, or performance counters.
CheckMEM -a MaxWarn=80% MaxCrit=90% ShowAll type=physical
Can you Pls. elaborate more on this.
you can monitor metrics such as these with more detail or in different fashions with SNMP,custom plugins, or performance counters.
You can monitor system memory usage through a wide variety of check mechanisms, basic standard nrpe or check_nt checks are only the ground level of systems monitoring. You could find the performance counter you want to monitor within windows and then use a custom NRPE check to return the data to you. Are you looking for an example of this?
