Graph 2 days or more is not displayed

  • Hi, Everyone


    I have having problems displaying metrics on Graphite when the date is "yesterday" or more days ago. I am collecting a lot of metrics, such as cpu, mem, disk, processes, and so on, working fine. However, the last two metric added are the reason for this thread.



    For collect metrics I use collectd, then it sends to Riemann engine for distribution and alerting purposes. Riemann sends streams to Graphite in order to store metrics. Finally, Grafana queries to Graphite for time-series (with data) and graph them.



    I have some schemas of retention for all metrics.


    storage-schemas.conf




    This empty graph is showed when I request for 2 or more days.

    2 days




    1 day


    The graph is successful when i request it for 1 day.

    Whisper file


    Shows correctly storage-schemas configuration and it has information.





    Thanks for your help.

    1. Graphite only shows 1 day of data, even after adjusting the storage-schemas.conf
    2. graphite not graphing some metrics

    I have been checked my .wsp files. I picked-up the first entry and then I have transformed in a human-redeable date. So, the .wsp file only has 24 hours of inforrmation (3.4 MB). My cuestion is: Have I to resize (increase) the .wsp file?

    Greetings!

  • Have I to resize (increase) the .wsp file?

    Yes you need to resize the wsp file.


    In the wsp file is defined how long and hwo often a timepoint is written to it.



    Btw in the thread you visited before, number 3 could be helpful here.


    A few months ago i wrote a similar litte guide to change the whisper files:

    Can't view last 30days log in grafana

  • Thanks for the link, birkch.


    I will wait for some hours in order to check it.


    Please, let me understand something. I know that the file size and timepoints saved in .wsp file are determinated by store-schemas.file. In my configuration I have setted a vast retention period, so why it behave as a default (24 hours) storage-schemes configuration?



    Thanks a lot!

  • I have solved thi issue.


    My metric pushing was different that my retention pattern (storage-schemas) and my aggregate (storage-aggregate) had xFileFactor=.5. I ensure that in my .wsp file there not were null values.
