LUN and FileSystem Display Issue

[iFeelUing]

Hi all,

I met a problem recently. I use Nagios to monitor my storage device and the web page only display the first 20 LUNs and FileSystem at its part.

the web page also shows the following information: "There are 57 FileSystems are normal : Only 20 pieces of data can be displayed, due to the display limit. " "There are 287 LUNs are normal : Only 20 pieces of data can be displayed, due to the display limit. "

How can I view the other LUNs and FileSystem? the web page don't provide a button "next page" or something like this.

I have no idea what you're talking about, quite frankly.

What is "the web page"? What are the plugins you're using? How have you configured the host/services?

Nagios Core definitely has next/previous pages on the host/services pages (if that's what you're referring to).

Can you maybe share a screenshot?

Hi sir,

"the web page" is the Nagios monitoring web page. And the plugin is powered by Huawei company. I also think that Nagios should support splitting page functional. but we can only see the first 20 LUNs in fact. like this:

I have 3000+ LUNs, but I only can see the first 20 LUNs.

Can you run the plugin and count the character output please?

/path/to/your/plugin | wc -m

Hello sir,

what kind of character output do you want? because the command you provided seems incomplete. BTW, the plugin is installed to /usr/local/nagios.

I don't know why the web page only display 20 LUNs and filesystems, at the detail information page of "StorageLUN", it's still display 20 LUNs and can't go to the next page. like this:

is there any way to increase the max value of display? and how can I view the remain LUNs?

what kind of character output do you want?

Here's a plugin with full output:

/usr/local/nagios/libexec/check_ifoperstatus -H 10.25.4.3 -C public -k 1 -v 2 -p 161
OK: Interface tengigabitethernet1/0/1 (index 1) is up.

@hedenface wants you to pipe that to wc -m so it can count how many characters are in your output, using the example I just gave:

/usr/local/nagios/libexec/check_ifoperstatus -H 10.25.4.3 -C public -k 1 -v 2 -p 161 | wc -m
55

The number 55 is the amount of characters that was in the output.

We suspect your output for a single service is exceeding some built in limitation, we need to know how many characters are being produced by the plugin.

Hello Sir, the output is below.

/usr/local/nagios/libexec/check_ifoperstatus -H 8.44.160.97 -C public -k 1 -v 3 -p 161 | wc -m
309

So the example I gave was just an example, you need to replace everything before | wc -m with your plugin and arguments, the one that is generating all the output.

/usr/local/nagios/your_plugin with_arguments | wc -m

Hi Sir,

I run the command using Huawei plugin:

[root@localhost huawei]# python checkarray.py checklun -h 8.44.160.97 -c huawei@123 -v v3 -p 10062 |wc -m
1206

So if you just run the following what is displayed?

python checkarray.py checklun -h 8.44.160.97 -c huawei@123 -v v3 -p 10062
