PATROL Agent configuration variables

/EnvList

Type of monitoring:

• Availability only=1
• HADOOP system controlled=2
• Customer collection data Selection=3

The numbers of monitored groups separated by ',' separator, for example if you insert number 1,2 means you want to monitor only HADOOP groups 1 and 2, each group number exist in its own xml file under Patrol3/btq/xml

This will disable the creation of the instance on the PATROL tree view

Valid values: True or 1, False or 0

When this variable is set to zero, it will disable the creation of the instance on the PATROL tree view

Valid values: True or 1, False or 0

This variable will generate diagnostic report for support, value 1 will generate diagnostic report

Valid values: True or 1, False or 0

This variable will enable or disable PSL and Java logging

Valid values: Enable = 1, Disable = 0

This variable sets the locale of Hadoop environment. The locale of Hadoop environment must be declared as <language>_<country> for example en_US.

If you do not insert this pconfig variable then the current locale of the Java collector will be used.

If you do not succeed in retrieving the current locale from Java then the default locale, en_US, will be used.

This variable indicates the change in the operating system credentials

Valid values:

1-indicates that the OS credentials are changed

0-indicates that there is no change to the OS credentials

This variable indicates the Hadoop vendor order. The variable should be set to the number of the vendor.

Valid vendor values:

• Apache Hadoop- 1
• IBM BigInsights- 2
• MapR- 3
• Cloudera- 4
• Horton- 5

This variable indicates the Hadoop port. The port can be NameNode, SecondaryNameNode, ResourceManager, DataNode, JobHistory, NodeManager, JobTracker or TaskTracker port.

This variable indicates a change in the Hadoop credentials

 Valid values:

1 - Indicate that the Hadoop credentials are changed

0 - Indicates that there is no change to the Hadoop credentials

This variable indicates the type of protocol used to connect to the Hadoop environment.

Valid values:

0 - Indicates connection to Hadoop with a NON secure mode (HTTP protocol)

1 - Indicates connection to Hadoop with a secure mode (HTTPS protocol)

This is the SSL trust store file. For example: C:\\sec\\truststore.jks

Enter this value only when the isSecure pconfig variable is set to 1 (HTTPS protocol)

This variable indicates if the change in the SSL trust store password

Valid values:

1- Indicates that the SSL trust store password is changed

0- Indicates that there is no change to the SSL trust store password

This variable will contain a comma-separated list of regular expressions, host names and IP addresses of the data nodes that will be included for monitoring. The regular-expression conforms to the regular expressions defined by Java.

This variable will contain a comma-separated list of regular expressions, host names and IP addresses of the data nodes that will not be included for monitoring. The regular-expression conforms to the regular expressions defined by Java. If the /includedDataNodes pconfig variable is defined, the /excludedDataNodes variable will not be available.

This variable will contain a comma-separated list of regular expressions, host names and IP addresses of the node managers that will be included for monitoring. The regular-expression conforms to the regular expressions defined by Java.

If you have task trackers in your environment, this variable will be used to filter task trackers.

This variable will contain a comma-separated list of regular expressions, host names and IP addresses of the data nodes that will not be included for monitoring. The regular-expression conforms to the regular expressions defined by Java. If the /includedNodeManagers pconfig variable is defined, the /excludedNodeManagers variable will not be available.

If you have task trackers in your environment, this variable will be used to filter task trackers.

Set this collector value in seconds. The Hadoop collector cycle, for each collector exists in $PATROL_HOME/Patrol3/btq/collectors/collectors.xml

You can change the collector cycle. Once the pconfig variable cycle is defined, the KM will use the defined cycle instead of the default cycle in the XML.

The cache cycle will be equal to the received collector's cycle.

If this variable is set to True or 1, the collectors output will be added to the cache thread. The cache thread will be responsible for sending data to PATROL Agent if the collector fails to collect data. The cache thread will display old values of the parameters for a specific period of time before it stops sending values to PATROL Agent.

When this variable is set to False or 0, the collector will send the output directly to PATROL Agent, without any caching. This variable is also defined in the $PATROL_HOME/Patrol3/btq/conf/btq.properties file.
