Allows you to query events in the system.

EventsResourceApi apiInstance = new EventsResourceApi();
Integer maxResults = 100; // Integer | The maximum number of events to return.
String query = "query_example"; // String | The query to perform to find events in the system. It accepts querying the intersection of a list of constraints, joined together with semicolons (without spaces). For example: </p> <dl> <dt>alert==true</dt> <dd>looks for alerts.</dd> <dt>alert==true;attributes.host!=flaky.mysite.com</dt> <dd>looks for alerts, but exclude those with the host attribute of \"flaky.mysite.com\".</dd> <dt>category==log_event;attributes.log_level==ERROR</dt> <dd>looks for error log events.

You can also query by event attribute values using the <em>attributes.*</em> syntax. Values for date time fields (e.g. <em>timeOccurred</em>, <em>timeReceived</em>) should be ISO8601 timestamps. <p> The other valid comparators are <em>=lt=</em>, <em>=le=</em>, <em>=ge=</em>, and <em>=gt=</em>.

Integer resultOffset = 0; // Integer | Specified the offset of events to return.
try {

Parameters

Name Type Description Notes
maxResults Integer The maximum number of events to return. [optional] [default to 100]
query String The query to perform to find events in the system. It accepts querying the intersection of a list of constraints, joined together with semicolons (without spaces). For example:

alert==true
looks for alerts.
alert==true;attributes.host!=flaky.mysite.com
looks for alerts, but exclude those with the host attribute of "flaky.mysite.com".
category==log_event;attributes.log_level==ERROR
looks for error log events. Event attribute matching is case sensitive.
attributes.service==hbase1;content==hlog
looks for any events from the "hbase1" service that mention "hlog".
attributes.service==hbase1;content!=hlog
looks for any events from the "hbase1" service that do not mention "hlog".
A query must not contain only negative constraints (!=). It returns empty results because there is nothing to perform exclusion on.
attributes.role_type==NAMENODE;severity==critical important
looks for any important or critical events related to all NameNodes.
severity==critical;timeReceived=ge=2012-05-04T00:00;timeReceived=lt=2012-05-04T00:10
looks for critical events received between the given 10 minute range.
When polling for events, use timeReceived instead of timeOccurred because events arrive out of order.
You may query any fields present in the ApiEvent object. You can also query by event attribute values using the attributes.* syntax. Values for date time fields (e.g. timeOccurred, timeReceived) should be ISO8601 timestamps.

The other valid comparators are =lt=, =le=, =ge=, and =gt=. They stand for "<", "<=", ">=", ">" respectively. These comparators are only applicable for date time fields.

[optional]
resultOffset Integer Specified the offset of events to return. [optional] [default to 0]
