Symptoms

We have a customer with PA Subscription #SUB_ID - domain DOMAIN.TLD is associated with the subscription

PBA-S Top > Account Director > Subscription Manager > Subscriptions > #SUB_ID > Domains

Several mailboxes exist in the domain, they are shown in CP:

PBA-S > Top > Account Director > Subscription Manager > Subscriptions > #SUB_ID > Account #ACC_ID > Log in to CP > Mail
--->8---
MAIL1@DOMAIN.TLD                        
MAIL2@DOMAIN.TLD                     
MAIL3@DOMAIN.TLD                      
MAIL4@DOMAIN.TLD                         
MAIL5@DOMAIN.TLD                     
---8<---

But resource "Number of mailboxes" is not updated in PBA-S subscription - it still has value 0:

PBA-S > Top > Account Director > Subscription Manager > Subscriptions > #SUB_ID > Resources > Show Advanced Options
--->8---
Number of mailboxes (number_of_mailboxes)       Current value 0 unit, Included value 0 unit
---8<---

When the customer will be charged for resource overusage?

Cause

Resource "Number of mailboxes" is not updated in PPA:

PPA > Top > Operations Director > Customers > #PPA_ACC_ID > Subscriptions > #PPA_SUB_ID > Resources
--->8---
1000318 Number of mailboxes     0 unit 1000 unit 1000 unit              July 01, 2013 12:11
---8<--- 

Because periodic task "Sync resource usage" fails in PPA:

PPA > Top > System > Task Manager > Periodic
--->8---
Sync resource usage     August 08, 2013 03:52:02        3600 second(s)  Rescheduled
---8<---

Run periodic task "Sync resource usage" in PPA. If the task fails, check log /var/log/poa.debug.log for the reason of the failure.

Resolution

In PBA-S statistics are gathered by task #40 "Update POA nodes stats info" periodically (defined by times in poa_sync_time table).

mysql> select * from poa_sync_time;
+-------+---------------------+---------------------+---------------------+---------------------+
| hw_id | res_usage_sync      | subscr_sync         | serv_tmpls_sync     | conflicts_sync      |

To verify resource usage is updated - change res_usage_sync to the time in the past and run the task through GUI. Here is the record in PBA-S log about successful resource usage update for PPA subscription 18:

In PBA-S the resource usage statistics for PPA subscription is added into table poa_stat_history:

mysql> select psh.subscr_id, pr.poa_res_id, pr.class_name, psh.total, from_unixtime(psh.last_update_ts) from poa_stat_history psh, poa_res pr where psh.subscr_id=<SUB_ID> and psh.res_id=pr.res_id group by psh.last_update_ts desc;
+-----------+------------+----------------------+-------+-----------------------------------+
| subscr_id | poa_res_id | class_name           | total | from_unixtime(psh.last_update_ts) |
+-----------+------------+----------------------+-------+-----------------------------------+
|  <SUB_ID> |    1000318 | plesk_mail.mailboxes |     5 | 2013-08-12 20:39:30               |
...

Statistic will be used for issue overusage invoice in billing day.
