Andrew,

Thank you for your answer but after attempting to execute your steps I get the following errors:

[root@ps02 esmond]# cd /opt/esmond
[root@ps02 esmond]# source /opt/rh/python27/enable
[root@ps02 esmond]# . bin/activate
(esmond)[root@ps02 esmond]#
(esmond)[root@ps02 esmond]# python ./util/ps_remove_data.py -c /home/gridlafex/clear_data.conf

Any idea of what can be the problem?

Subject: Re: [perfsonar-user] How to clean esmond/perfsonar/archive ????

Hi,

If you don't want to wait for teh GUI to clear things out after a few days. You can do the following:

1. Download the config file attached to the host with the data you want deleted

2. Run the following commands to delete everything older than 2 days on the host with the data you want deleted:

cd /opt/esmond

source /opt/rh/python27/enable

. bin/activate

python ./util/ps_remove_data.py -c clear_data.conf

In the last command you will likely need to change clear_data.conf to the full path of the file you downloaded from this email. If you want to change the time range, adjust the '"expire":          "2"' line in the file to be another value (the value is in days).

Hope that helps,

Andy

Dears,

On the "Throughput / Latency Graphs" page (https://ps02.cat.cbpf.br/serviceTest/psGraph.cgi) I have a lot of tests that aren't being handled anymore.

In http://ps02.cat.cbpf.br/esmond/perfsonar/archive/?format=json I can see all of them, but how could I erase them?
