### Changing data profile averages
|
|
|
|
The Cacti GUI allows you to change the averages on a specific Data source
|
|
profile some setups require a higher resolution of data and you may want to
|
|
change the averaging to keep the most data this will come with a cost of storage
|
|
due to the bigger sized RRDfile
|
|
|
|
To do this follow these steps
|
|
|
|
#### Method 1 - New system without any hosts
|
|
|
|
1. Login to Cacti
|
|
|
|
2. Click on Presets >> Data Profiles
|
|
|
|
3. Select the profile you want to edit i.e 1 minute collection
|
|
|
|
4. Select the period which you want to edit i.e weekly
|
|
|
|
5. If you wish to change the average select the aggregate level for 1 minute
|
|
you will be able to go as low as 5 Minutes
|
|
|
|
6. You will need to edit the Rows amount to match the data retention you want
|
|
to set after this period the data will be averaged out to the monthly graph
|
|
|
|
7. Save config and generate graphs
|
|
|
|
#### Method 2 - Existing device(s) on system
|
|
|
|
This is a more data destructive route and it will depend on your situation. If
|
|
you have graphs already on cacti you will not be able to use Method 1. An option
|
|
if you do not care about the graphs is to either remove the graphs via the gui
|
|
or run the following script `/cli/php remove_graphs.php with the --all`
|
|
function.
|
|
|
|
This will REMOVE ALL THE GRAPHS and you can then follow the steps outlined in
|
|
Method 1 to change the profile how you like
|
|
|
|
### Data profile Rows Calculation
|
|
|
|
The rows calculation take in to account the following
|
|
|
|
Rows = Aggregate level * hours
|
|
|
|
Example
|
|
|
|
1 Minute aggregate level storing for 3 days ( 72 hours)
|
|
|
|
(Aggregate level)60 * 72 ( 72 hours) = 4,320
