APEL Deployment

We are changing the accounting system used in our infrastructure, from DGAS to APEL and the procedure is quite simple.

Each resource centre needs to install a new node (the APEL Publisher) which receives the accounting information sent from the CE(s) by the APEL parser. Then the APEL publisher sends the data to the central database using the messaging infrastructure.

We are testing two scenarios:

  • the accounting data are sent directly to the central databse (canonic installation)
  • the accounting data are sent to FAUST and to the central database

Registration

you need to register the APEL publisher in the GOC-DB and ask the APEL team to authorize the publisher in sending the data. Follow the instructions here https://wiki.egi.eu/wiki/MAN09_Accounting_data_publishing

APEL Publisher Installation and Configuration

Follow the EMI3 generic installation guide and the APEL one https://twiki.cern.ch/twiki/pub/EMI/EMI3APELClient/APEL_Publisher_System_Administrator_Guide.pdf

Example of client.cfg Example of sender.cfg

Don't start the apelclient and don't set it in the daily cron until you receive the OK by the APEL team.

Remember to use the testing queue of the broker network during the first days

Sending the data to FAUST

in case of the second scenario, follow the instructions https://github.com/andreaguarise/ssm-dupl-send

this mean that instead of apelclient script, you have to use the ssm-dupl-send.sh one

APEL Parser Installation and Configuration

Install and configure the APEL parser on each computing element of your resource centre.

Follow the EMI3 generic installation guide and the APEL one https://twiki.cern.ch/twiki/pub/EMI/EMI3APELClient/APEL_Parsers_System_Administrator_Guide.pdf

Here an example of parser.cfg file

Don't make parse the blah and batch server logs older than one month before to the current one.

you can launch the apelparser script after the setting-up of the apelclient database

What about DGAS sensors?

you may leave active the dgas sensors: just request to NGI_IT to disable the data sending from DGAS to APEL for your site
