Can't view last 30days log in grafana

  • Hello,


    I have got a number of problems. I have setup icinga2, icingaweb2, graphite, graphite module in icingaweb2. The problems are:


    • icingaweb2 is not displaying graphite graph using graphite-module though I can see graph in graphite itself
    • can't view last 30days log in grafana. (important)



    last one is more important for me than number one. I have googled and found that "retentions" period should be changed. I have change the days and restarted carbon-cache, reloaded httpd but it is showing last one day graph only. My config file (/etc/carbon/storage-schemas.conf) looks as below:



    I already changed last one ([default_1min_for_1day]) retentions to 30d but it is also not working. Can anyone help? :(

  • The problem is that the performance data is stored in files and these files are not expanded if you change the carbon configuration.


    Example:


    These files keep the same size, you have to expand them.


    For this you have to use the utility "whisper-resize"
    Example:

    Code
    1. [root@hostname]# whisper-resize
    2. Usage: whisper-resize path timePerPoint:timeToStore [timePerPoint:timeToStore]*
    3. timePerPoint and timeToStore specify lengths of time, for example:
    4. 60:1440 60 seconds per datapoint, 1440 datapoints = 1 day of retention
    5. 15m:8 15 minutes per datapoint, 8 datapoints = 2 hours of retention
    6. 1h:7d 1 hour per datapoint, 7 days of retention
    7. 12h:2y 12 hours per datapoint, 2 years of retention

    Now you can resize with the following command:


    Code
    1. whisper-resize 60:7d /path/to/file.wsp


    I hope this helps you. :)


    PS: please have a look at the file rights if the performance data does not change.
