Hands-On Session: Monitoring System Collector Server (MON) Installation and Configuration Regional SEE-GRID-SCI Training for Site Administrators Institute of Physics Belgrade March 5-6, 2009 Vladimir Slavnic Institute of Physics, Belgrade Serbia slavnic@scl.rs 1 The SEE-GRID-SCI initiative is co-funded by the European Commission under the FP7 Research Infrastructures contract no. 211338

MON RGMA-based monitoring system collector server Relational Grid Monitoring Architecture - R-GMA Works in conjunction with batch system (CE)‏

Prerequisites 1/2 Installation of operating system (SL4)‏ NTP installation and configuration check ntp.conf , ntp.drift, ntp.drift.TEMP in /etc Java installation

Prerequisites 2/2 Repository configuration‏ Install lcg-CA Get repos from local repository (http://rpm.scl.rs/yum.conf/)‏ Example for MON packages: cd /etc/yum.repos.d/ wget http://rpm.scl.rs/yum.conf/scl-glite-MON.repo Install lcg-CA Get host certificates hostcert.pem, hostkey.pem in /etc/grid-security/

gLite MON installation Install gLite packages: yum install glite-MON Install mysql-server : yum install mysql-server

YAIM node configuring Relevant entries in site-info.def : MON_HOST=mon.$MY_DOMAIN REG_HOST=gserv1.ipp.acad.bg MYSQL_PASSWORD=some_good_password APEL_DB_PASSWORD="APELDB_PWD" Execute configuration with: /opt/glite/yaim/bin/yaim -c -s <path to site-info.def> -n glite-MON

Testing configured system Execute server check script on MON node: /opt/glite/bin/rgma-server-check Try to connect to mysql base : mysql -u accounting -p Try to connect to the Server using the following address to your web browser: https://<MON URL>:8443/R-GMA/ Try to manually publish data from computing element node (use the scripts from crons) and observe logs

SG Accounting Client 1/3 Transmits aggregated accounting information to gserv1.ipp.acad.bg MON properly installed mysql -u root –p mysqlrootpasswrd GRANT SELECT on accounting.* to 'tomcat4'@'MONBOXHOSTNAME' identified by 'STRONGPASSWORD'; CREATE DATABASE tmp; GRANT SELECT, INSERT, UPDATE, DELETE, DROP, ALTER, CREATE TEMPORARY TABLES ON tmp.* TO 'tomcat4'@'MONBOXHOSTNAME';

SG Accounting Client 2/3 mpi_publisher-1.0-RHEL4.noarch.rpm installs on CE (if site supports MPI)‏ accounting_publisher-2.0-RHEL4.noarch.rpm installs on MON su – tomcat edit jvr.sh

SG Accounting Client 3/3 Only few lines to change: DBHOSTNAME=localhost DBUSERNAME=accounting (or tomcat4)‏ DBPASSWORD=… DBSITENAME=AEGIS08-PHY-DEMO Try to publish: ./jvr.sh https://gserv1.ipp.acad.bg:8443/Welcome/
