Abstract

A master monitor spawns a local monitor in each node of a server cluster. Each local monitor, responsive to a database event, determines a metric of a performance-related variable. A maximum period between measurements may be imposed to reduce irrelevant results, as may a minimum period. The metric may be stored in a measurement file on the respective node and/or may be reported to the master monitor. The master monitor may make any reported metrics available to a user via a front end.

Claims

1. A server cluster monitoring system comprising:

a master monitor configured to run on a first node of a server cluster, the server cluster being configured to host a massively parallel database system including a database management system (DBMS) accessible via a front end; and

a local monitor spawned on each node of a server cluster by the master monitor and configured to determine a value of a respective performance-related variable of the node for a respective predefined period, the local monitor further being configured to write the determined value to a local file on a respective storage device of the respective node.

2. The system of claim 1, wherein the respective predefined period is a time elapsed since a previous invocation of the respective local monitor.

3. The system of claim 1, wherein the respective predefined period is defined by a user.

4. The system of claim 1, wherein the respective predefined period includes at least one of a predefined minimum value or a predefined maximum value.

5. The system of claim 1, wherein the local monitor obtains a value of the performance-related variable from the DBMS.

6. The system of claim 1, wherein the local monitor obtains a value of the performance-related variable from an operating system of a node server.

7. The system of claim 1, wherein the local monitor further determines a respective node metric based on the respective performance-related variable.

8. The system of claim 3, wherein the local monitor determines a metric based on a change in value of the performance-related variable during the predefined period.

9. The system of claim 1, wherein the local monitor is further configured to report to the master monitor.
