Using the Logpull service

IBM customers can access the Logpull service on Enterprise accounts. This service allows users to consume request logs over HTTP using the Logpull command. These logs contain data related to the connecting client, the request path through the network, and the response from the origin web server.

Enabling log retention

Edge logs are not retained by default. Before you can pull logs using the Logpull CLI, you must enable log retention. To do so, you must check the current setting, then turn log retention on or off.

To check whether log retention is currently turned off, use the log-retention CLI:

ibmcloud cis log-retention DNS_DOMAIN_ID

If the output shows that the flag is off (default), update the setting as follows.

ibmcloud cis log-retention-update DNS_DOMAIN_ID --flag on

Logpull use cases

Getting logs based on RayID

If you receive an error message after running a command, you can use the RayID provided in the response header to get the logs related to the command.

If you have a RAY_ID with -XXX on the end, be sure to remove it. For example, 12ab34cdef567gh8-XXX becomes 12ab34cdef567gh8.

Use the following command for the request:

ibmcloud cis logpull DNS_DOMAIN_ID --ray-id RAY_ID

The response follows:

{
    "ClientIP": "68.278.11.89",
    "ClientRequestHost": "testing.logpull.com",
    "ClientRequestMethod": "GET",
    "ClientRequestURI": "/var/www",
    "EdgeEndTimestamp": 1545155129703000000,
    "EdgeResponseBytes": 1935,
    "EdgeResponseStatus": 403,
    "EdgeStartTimestamp": 1545155129696000000,
    "RayID": "48b371889c489b2c"
}

Getting logs based on time duration

If you receive an error message after running a command, but do not know the RayID of the response, you can use a time duration to get all logs for the time period when the error occurred.

Use the following command for the request:

ibmcloud cis logpull DNS_DOMAIN_ID --start 2019-01-02T01:00:00+00:00 --end 2019-01-02T01:00:00+00:00

Where --startand--end` is entered as a UNIX timestamp (in seconds or nanoseconds), or as an absolute timestamp that conforms to RFC 3339, with a time duration of a minute or an hour.

The response follows:
