Abstract

Certain example embodiments relate to a monitoring system for monitoring the operation of distributed computing components. The monitoring system includes a registry for storing descriptions of the computing components and at least one associated service-level agreement (SLA) specifying at least one performance requirement; a compiler for generating at least one first and second continuous query based on the information stored in the registry; and a complex event processing (CEP) engine for executing the at least one first continuous query on input events indicating actions performed by the computing components and corresponding performance information, and for producing at least one output event indicating a violation of at least one SLA. The CEP engine also executes the at least one second continuous query on input events indicating a violation of at least one SLA, and produces at least one output event indicating a relationship between at least two SLA violations.

First claim

What is claimed is:

1. A monitoring system for monitoring operation of a plurality of distributed computing components, the monitoring system comprising:
at least one processor and a memory;
a registry stored in the memory and configured to store (a) descriptions of the plurality of computing components and (b) a plurality of service-level agreements (SLAs) where each one of the plurality of SLAs specifies at least one performance requirement for at least one of the plurality of distributed computing components;
a compiler configured to generate at least a first and a second continuous query based on the information stored in the registry; and
a complex event processing (CEP) engine, operating on the at least one processor, configured to:
execute the first continuous query on input events indicating actions performed by the plurality of distributed computing components and corresponding performance information;
determine, as part of execution of the first continuous query, that a violation of a first SLA of the plurality of SLAs has occurred and, in accordance with determination of violation of the first SLA, output a first event indicating the violation of the first SLA;
determine, as part of execution of the first continuous query, that a violation of a second SLA of the plurality of SLAs has occurred and, in accordance with determination of violation of the second SLA, output a second event indicating the violation of the second SLA;
execute the at least one second continuous query on input events indicating violations of at least some of the plurality of SLAs including the first event and the second event;
determine, as part of execution of the second continuous query and based on the first and second events, a relationship exists between the violation of the first SLA and the violation of the second SLA; and
produce and output, in accordance with determination of the relationship between the violation of the first SLA and the violation of the second SLA, an event that indicates the relationship,

wherein determination of the relationship between the violation of the first SLA and the violation of the second SLA is based on 1) temporal correlation of the violation of the first SLA and the violation of the second SLA; or 2) a defined dependency between the at least one distributed computing component associated with the violation of the first SLA and the at least one distributed computing component associated with the violation of the second SLA,
wherein the first event and/or the second event comprise(s) data about the time when the corresponding violation was detected, which violation occurred, and/or measured values.

2. The monitoring system of claim 1 , wherein the descriptions of the plurality of computing components in the registry comprise relationship information indicating a dependency between two computing components of the plurality of computing components.

3. The monitoring system of claim 2 , wherein the at least one performance requirement for the first SLA specifies performance for a single call of the associated computing component and wherein the first event indicates violation of the single call.

4. The monitoring system of claim 2 , wherein the at least one performance requirement for the first SLA specifies performance for multiple calls of the associated computing component and wherein the first event indicates violation of the requirement for performance for multiple calls.

5. The monitoring system of claim 1 , wherein the at least one performance requirement is indicative of response time, availability, processing time, reliability, and/or throughput.

6. The monitoring system of claim 1 , wherein the at least one computing component is a service, a web service, an infrastructure component, and/or a database.

7. The monitoring system of claim 1 , wherein the compiler is configured to generate the first and/or the second continuous query when a lifecycle state of at least one associated SLA is set to productive.

8. The monitoring system of claim 1 , wherein each one of the plurality of SLAs comprises one or more service level objectives (SLOs) and wherein the compiler is configured to generate a continuous query for each SLO.

9. The monitoring system of claim 1 , wherein the first SLA specifies at least one required action to be performed upon detection of an SLA violation.

10. The monitoring system of claim 1 , further comprising a graphical user interface configured to enable a user to modify the information stored in the registry.

11. A method for monitoring operation of a plurality of distributed computing components, the method comprising:
storing (a) descriptions of the plurality of computing components and (b) a plurality of service-level agreements (SLAs) where each one of the plurality of SLAs specifies at least one performance requirement for at least one of the plurality of distributed computing components;
generating at least a first and a second continuous query based on the information stored in the registry;
executing the first continuous query on input events indicating actions performed by the plurality of distributed computing components and corresponding performance information;
determining, as part of execution of the first continuous query, that a violation of a first SLA of the plurality of SLAs has occurred and, in accordance with determination of violation of the first SLA, output a first event indicating the violation of the first SLA;
determining, as part of execution of the first continuous query, that a violation of a second SLA of the plurality of SLAs has occurred and, in accordance with determination of violation of the second SLA, output a second event indicating the violation of the second SLA;
executing, in connection with at least one processor, the at least one second continuous query on input events indicating violations of at least some of the plurality of SLAs including the first event and the second event;
determining, as part of execution of the second continuous query and based on the first and second events, a relationship exists between the violation of the first SLA and the violation of the second SLA; and
producing and outputting, in accordance with determination of the relationship between the violation of the first SLA and the violation of the second SLA, an event that indicates the relationship,
wherein determination of the relationship between the violation of the first SLA and the violation of the second SLA is based on 1) temporal correlation of the violation of the first SLA and the violation of the second SLA; or 2) a defined dependency between the at least one distributed computing component associated with the violation of the first SLA and the at least one distributed computing component associated with the violation of the second SLA,
wherein the first event and/or the second event comprise(s) data about the time when the corresponding violation was detected, which violation occurred, and/or measured values.

12. The method of claim 11 , wherein the descriptions of the plurality of computing components in the registry comprise relationship information indicating a dependency between two computing components of the plurality of computing components.

13. The method of claim 12 , wherein the at least one performance requirement for the first SLA specifies performance for a single call of the associated computing component and wherein the first event indicates violation of the single call.

14. A non-transitory computer readable storage medium tangibly storing a computer program comprising instructions for implementing a method in accordance with c
