Access Logs

Every running MongoDB instance collects logs from MongoD. Currently, there is no option to change this configuration. The log messages are shipped to a central storage location with a retention policy of 30 days.

Using the cluster ID, you can access the logs for that cluster via the API.

Endpoint

Use the following endpoint to get logs: https://api.ionos.com/databases/mongodb/clusters/{clusterId}/logs

Note: The sample cluster UUID is 498ae72f-411f-11eb-9d07-046c59cc737e.

The endpoint for fetching logs has four optional query parameters:

Parameter	Description	Default value	Possible values
start	Retrieve log lines after this timestamp (format: RCF3339)	30 days ago	between 30 days ago and now (before end)
end	Retrieve log line before this timestamp (format: RFC3339)	now	between 30 days ago and now (after start)
direction	Direction in which the logs are sorted and limited	BACKWARD	BACKWARD or FORWARD
limit	Maximum number of log lines to retrieve. Which log lines are cut depends on direction	100	between 1 and 5000

If you omit all parameters, you will get the most recent 100 log messages.

The following example shows how to receive only the first two messages after 12:00 a.m. on January 5, 2022:

Request

curl --include \
    --request GET \
    --user "[email protected]:Mb2.r5oHf-0t" \
    --header "Content-Type: application/json" \

Response

The response contains the log messages separated per instance and looks similar to this:
