How Fluentd-based Snapshot Manager logging works
When you install or upgrade Snapshot Manager, the following changes occur on the Snapshot Manager host:
A new container service named
flexsnap-fluentd
is started on the Snapshot Manager host. This service is started before all the other Snapshot Manager container services. Theflexsnap-fluentd
service serves as thefluentd
daemon on the host.All the Snapshot Manager container services are then started with
fluentd
as the Docker logging driver.A
fluentd
configuration file is created at/cloudpoint/fluent/fluent.conf
.This file contains the output plug-in definitions that are used to determine where the Snapshot Manager logs are redirected for consumption.
Once all the infrastructure components are ready, each of the Snapshot Manager services begin to send their respective log messages to the configured Docker fluentd
logging driver. The fluentd
daemon then redirects the structured logs to the output plug-ins configured in the fluentd
configuration file. These logs are then sent to the /cloudpoint/logs/flexsnap.log
file on the Snapshot Manager host.
Note that the flexsnap.log
file gets rotated after the file size reaches a maximum of 100 MB. A total of 30 generations (rotated files) of the flexsnap.log
file are maintained. These conditions are applicable because of the new log file rotate (log-rotate-age
) and log size (log-rotate-size
) command options that are introduced in the fluentd command.
