Cheshire Cat Computing

Hello guys,

Just a question about 95th percentile and total feature.

I have combined 2 graphs together with the below:

routers.cgi*Graph[blah]: Combined Total
routers.cgi*Graph[blah2]: Combined Total

The 95th Percentile and total value is not displayed in the combined graph. . It displays in individual graphs such in this case blah and blah2.

any help appreciated.

regs,
ezat

This feature is available in v2.16beta5 and later.

Before this, percentiles and totals were not calculated in userdefined graphs.

Steve

thanks for the help.

On another note steve,

is it possible to retrieve a 95th percentile figure for a single month from say 5 months ago?

Can routers.cgi create a graph for a past particular month with 95th percentile and total?



regs,

Only if you enable the RRD Archiving feature. See the HOWTO for details on how to do this.

If you dont use RRD archiving, then after 1 month the RRD file no longer contains the necessary information to generate the percentile number for the past month.

This always causes confusion however I word it.

It means, from today back 1 calendar month. ie, if it is archived on 13th April, it is for the period 13 Mar -> 13 April.

The problem with previously saying 'last month' is that people thought it was the last calendar month -- ie, if run on 13th April, they thought it meant 1st March - 31st March, which is does not. Hence the 'rolling last month'.

Here, we run the RRD archive every night at 23:55. The expiry settings mean that we automatically keep a daily archive for the last 2 weeks, and the monthly archive (1st of each month) back for 2 years.
