app.mongodb.check-mongodb-alive

</td><td>

Monitors whether the MongoDB server is alive and creating alerts for the MongoDB server health status.

</td><td>

`commonchecks check-mongodb-alive -H db_host -p db_port` Where:

 -   `db_host` = Host where server is running.
-   `db_port` = Port to connect to the MongoDB server.

 Usage example: `command: commonchecks check-mongodb-alive -H 10.***.***.*** -p 27017`

</td><td>

`commonchecks check-mongodb -p {{.labels.params_port}} -H {{.labels.params_host}}`

</td><td>

`Check mongodb Alive OK`: Indicates that the server is in good health.

Event

</td><td>

app.mongodb.check-mongodb-metrics

</td><td>

Creates alerts for any of the MongoDB metrics, based on the threshold limit. To trigger the alerts for any MongoDB server metric, pass the whole metric name in the parameter.

</td><td>

`commonchecks check-mongodb-metrics -H Hostname -p port -w warning -c critical -d database -m MetricName` Where:

 -   `Hostname` = Host where server is running.
-   `port` = Port to connect to the MongoDB server.
-   `warning` = Warning threshold value.
-   `critical` = Critical threshold value.
-   `database` = Database name.
-   `MetricName` = Specific metric to monitor.

 Usage example: `command: commonchecks check-mongodb-alive -H 10.***.***.*** -p 27017`
