MongoDB is a cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas. MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License.
Prerequisites
- To monitor MongoDB, you need the credentials of the user with the roles “read” and “clusterMonitor”.
1. use admin
2. db.createUser({"user":"<username>","pwd":"<password>","roles":[{role:"read",db:"admin"},{role:"clusterMonitor",db:"admin"},{ role: "read", db: "local" }]})
- For Virtual Machines, install the Linux Agent.
Configuring the credentials
Configure the credentials in the directory /opt/opsramp/agent/conf/app.d/creds.yaml
mongodb:
- name: mongodb
user: <username>
pwd: <Password>
encoding-type: plain
labels:
key1: val1
key2: val2
