Nagios XI - Monitoring CPU Memory Swap Disk RO Disk Space

[scollins]

Hi,

Iv added all our servers to the nagios all looks good with the SSH & Ping services its now time to finish up with the rest of the server health checks.
Please advise if Nagios XI support the below monitoring functions including its monitoring parameters.
If so - I might need some assistance selecting the correct command in creating the service.

I would like to monitor our servers with the below checks, Can one set up these checks ??

- CPU Load Times (5min) … 5min + 10min [graph]
- CPU Idle (5min) … %Idle
¬ 4 x Thresholds = INFO 20% Idle
¬ 3 x Thresholds = WARNING 10% Idle
¬ 2 x Thresholds = CRITICAL 0% Idle

- Memory Utilization (5min) … %Utilized [graph]
- Swap Utilization (5min) … %Utilized [graph]
¬ 2 x Thresholds = INFO 20%
¬ 2 x Thresholds = WARNING 40%
¬ 2 x Thresholds = CRITICAL 90%

- Disk Capacity Utilization (5min) … %Utilized [graph]
¬ 2 x Thresholds = WARNING 80%
¬ 2 x Thresholds = CRITICAL 95%

- RO Disk State (T/F)
¬ Thresholds = CRITICAL = True

Also identify the ones that cannot be set up or configured.

Thanks,

While we will not set these up for you, we can guide you on what to do and where to go....


Are you wanting to check these statistics on Windows or a Linux based system? I'd recommend taking a look at this agent here, which will give you the ability to run a monitoring wizard against the server and get these metrics:

Hi, thanks for the reply

Our systems consists of various Linux flavours and windows systems - I will Study & implement the Link you provided and provide feedback upon completion.

Question 1.
Hi

I read the document and i see it requires a package installation on the node itself, we have over 600 Nodes so that process is abit painfull as we dont not have a option to mass install eg Red Hat Network.I was hoping you could guide me in the command option that you provide under configuration tab services add service and select the correct command for monitoring purposes.

Example

Check Command:
check_local_load | with respective arguments
$ARG1$ 5.0,4.0,3.0
$ARG1$ 10.0,6.0,4.0

Check Command:
check_local_swap | with respective arguments
$ARG1$ 20
$ARG1$ 10

Do you have these options for -> Memory Utilization ? Disk Capacity ? & Swap Utilization ?


Question 2.

How do you set up a alert to Notify you for INFO then a WARNING then if its CRITICAL ?

Thanks

Question 1.
These are generally setup through the wizards with the Arguments specified there. If you have many systems that are going to be setup the same way, you can run the Wizard for one of them to get it just how you like it, then run the Bulk Host Cloning Wizard to setup all the rest with the same thresholds.

Question 2.
Nagios XI has three different item
OK (INFO)
WARNING
CRITICAL

However, the OK, will only send notification if it is a recovery from a non-OK state
