foreword
With the continuous deepening of application informatization, long-term accumulated business data has become invaluable. Business data backup security is an important guarantee for business continuity; at the same time, business data also guides and becomes the most valuable scientific basis for business analysis. Therefore, people have built disaster recovery backup systems for business systems one after another. In the disaster recovery backup system, the real-time requirement of " data replication " has become the top priority. In the design of the disaster recovery system, the requirements from the production end to the disaster recovery must be strictly defined. The standard delay time (that is, the RPO indicator) allowed for duplicating business data on the terminal side ensures that in the event of a disaster recovery system switchover, the business data of the activated backup system has integrity and continuity.
Because the operation of the disaster recovery system and the operation of the data replication system will not attract widespread attention during the non-disaster period, even if an abnormality occurs, it will not affect the operation of the production system. , only to find that the business data of the backup system is incomplete, which will lead to very serious consequences.
This requires that the existing IT operation monitoring solution must be able to support the monitoring and management of the " real-time data replication " system at the same time. The business operation monitoring platform must monitor the RPO delay of all data replication groups in real time during the safe production period . Once it is found that it does not meet the disaster recovery design standards of the relevant business system, it should give an alarm in time and prompt which business switch will be affected.
Two new monitoring and management issues are proposed here:
1) The diversity of data storage and disaster recovery systems makes the industry have a variety of different data replication tools; existing IT operation monitoring solutions need to be compatible with various data replication tools;
2) The health of data replication should be an important part of the business health monitoring view just like infrastructure monitoring.
PIGOSS BSM provides a professional disaster recovery monitoring module to provide customers with a complete business reliability management solution, and uses disaster recovery monitoring indicators as a component of the business topology view to show a panoramic view of business availability and reliability monitoring and management.
1. Real-time monitoring scheme for DB2 data replication
DB2 data replication is usually achieved through the HADR professional data replication module. PIGOSS BSM not only provides RPO index monitoring (replication delay time) for HADR data replication groups , but also provides real-time monitoring of HADR operation status and performance. Support JDBC and AGENT two monitoring methods, click to view the data results of indicator collection
2. Real-time monitoring solution of GoldenGate for oracle data replication
Oracle's data replication is usually implemented through Oracle's supporting GoldenGate professional data replication module. PIGOSS BSM can monitor GoldenGate 's process status, data replication performance, extract process long transaction indicators and RPO delay time. Click the test button in the view to view the data result set collected by the indicator
3. Real-time monitoring solution for NAS data replication
NAS data replication is implemented through the SnapMirror module. PIGOSS BSM can monitor SnapMirror process status, status indicators, backup storage statistics, read and write statistics, file indicators and RPO delay. Click to view the data result set collected by the indicator
4. Support real-time monitoring of other data replication
In addition, PIGOSS BSM also supports real-time monitoring of data replication for ADG, Ceph, CommVault, Hacmp, InSpurKHA
