Custom Chart for Disk I/O per Host

Explorer

Hi ,

 

I am trying to create a custom chart for Disk I/O per host but i am getting o/p as mix like consist of Kb/second,Bytes/second.So i am trying to create report with uniform Unit like Bytes/second.So is there any compulsiion we can specify the unit like Kb/second

 

Tsquery used 

select (total_read_bytes_rate_across_disks+total_write_bytes_rate_across_disks) where hostname="hostname".

Hi nickk,

 

By default, the Y axis min and max values are determined automatically, to best fit the chart to the available space, and to be human readable - that's why it scales automatically across magnitudes.

Unfortunately, there is no way to change this behaviour at the moment.

 

Can you tell me what kind of report would you like to create actually?

 

 

cheers,

zegab

The units for each metric is statically defined. What you can do is to use '/1000' and etc to adjust the numbers to your needs.

Yes that i thought of but result is sometimes in Mb.Bytes and sometimes in Gb so can't hardcode as it gives usage of disk but meanwhile i am using metric  named Utilisation which gives result in percentage .
