dCache Local Monitoring at JINR

In accordance with the plans on construction of CMS Tier1 center at the JINR, the installation of 2 additional dCache systems has been accomplished. Thus, now 4 dCache systems are supported at the JINR. At other side, transition to the new dCache versions (2.2.24 and higher) gave a possibility to use the statistics module provided by the dCache system. Its features could be illustrated by the Fig.1


Fig.1 dCache statistics module page.

The statistics module provides a status of different dCache parameters. Statistics reports are generated automatically once a day or at any time by request and they available by dCache server web-interface at any time. Reports can be received for the periods of one day, a week, a month or an year. The following categories are presented: amount of written and read information, amount of transferred and received information, movers active time, exchange with cash-pools and “cost” of pools.

An example of statistics system graphics is presented at the Fig.2.

Built in statistical methods are convenient in use also because of a two-level system has been configured including the tapes. Thus, it makes possible to generate one-point statistical reports  independent of HSM system in use.

An old dCache monitoring system has removed from operation and an actual dCache local monitoring system is available at http://se-hd02-mss.jinr-t1.ru:2288/statistics/
