Release Notes 4.6.0

• Generic Rest Monitor for Nginx: Monitoring support is provided for Nginx. Two Nginx Monitors are added with new configuration UI:

1. 1. NginxPlusSlabPages
   2. NginxPlusSlabSlots

Nginx is a high-performance open-source HTTP server and reverse proxy, and an IMAP/POP3 proxy server. It can be used as a standalone web server, or serve in front of other web servers as a reverse proxy i.e is a device or service placed between a client and a server in a network infrastructure.

• Implementation of New Monitors for MongoDB Monitoring: The following stats are fetched now to know MongoDB health – performance stats, query and execution stats, session stats, and locks.

Configuration json for all the above monitors are bundled in MBean/XML directory of the controller:

1. 1. Execution Stats – MongoExecutionStat.json
   2. Session Stats – MongoSessionStats.json
   3. Config Stats – MongoDBParamConfig.json
   4. To fetch server name – MongoDBServerName.json

Old MongoDB monitors have also been migrated to new generic code of mongodb:

1. 1. CollectionStatsEx – MongoCollectionStat.json
   2. ReplicaStatsEx – MongoDBReplicaMonitor.json
   3. DBStatsEx – MongoDBStat.json

• Integration with DynaTrace: You can capture metrics of DynaTrace through the rest API as DynaTrace monitoring support is provided in ND. With this integration, you can monitor DynaTrace Host stats. In DynaTrace, you can generate a token from the UI and this token never expires. Then, you can use this token to generate the output or to get the metrics data.
• Support of Command Arguments for Generic Command Monitor: You can now configure command with arguments like this:

“input”: {
“actionStr”: “nsu_server_admin -s {Server} -c {cmd}”
}
And provide actual command arguments at runtime while configuring monitor with monitor argument
(-Q/–param)
-Q “{Server}=10.10.60.11,{cmd}=pwd”

You can configure any number of command arguments with comma-separated and can use any syntax for Key=Value matching. However, that Key should be the same at both places (config file and monitor arg).

• Highlighting the Selected Graph Type in “Open Chart Settings” for Graph Panels: When you select the graph type then the corresponding graphs are highlighted with color instead of the radio button in the Open Chart Settings options.
• Addition of One More Graph in JettyThread Monitor: One more graph is added in JettyThread monitor to show the “reservedThreads” attribute.

1. In addition, four graphs are added in JettyThreadStrategy monitor:
2. pCTasksConsumed
