[Xymon] False alert on disk

[Neil Simmonds]

Hi all, 

 

I'm getting a strange false alert on one of our Xymon systems.

 

We got an alert for disk and the webpage output looks like this,

Notice that some of the lines seem to have spurious line feeds, there is a
square bracket that has appeared and we have some letters missing. 

 

When I clicked on the link for the client data this is what the disk section
looks like.

As you can see, there doesn't appear to be anything wrong with this. 

 

The only difference that I am aware of with this is that on our system where
we are not seeing this, we are running Xymon 4.3.4 on CentOS 5.6 and on the
one where we are seeing the issue we are running Xymon 4.3.4 on CentOS 6.3

 

Has anyone ever seen this kind of behaviour?

 

Thanks, Neil.
