Manually Rotating the Aerospike Log File

Log rotation is managed by systemd-journald, and usually you don't have to pay attention to it. However, there are some use cases for manual file rotation. You might want to rotate a log to free up space, or to separate debugging information from routine operations.

Follow these steps to manually rotate the log file. The following steps use /var/log/aerospike.log for the example log file.

  1. Move the existing log file to a new location:
mv /var/log/aerospike.log /var/log/aerospike-old.log
  1. Find the asd (Aerospike daemon) process ID:
pidof asd

The expected output is a process number, for example:

3513

In non-systemd environments it can be found in the pidfile:

cat /var/run/aerospike/asd.pid
  1. Send a SIGHUP to the asd process:
    kill -s SIGHUP 3513

In the old log file you will see the following message:

SIGHUP received, rolling log

This should be the last message in the file. Aerospike will re-create the original log file, and all new messages will appear in it.

Finding the log IDs and log file location​

Use asinfo to find the log IDs, and their locations:

asinfo -v "logs"

Expected output:

0:/var/log/aerospike.log;1:stderr

The example output shows that there is a log file at /var/log/aerospike.log, and a second logging stream directed to stderr. Refer to Configuring Log Files../configure_log_files.md) for more information.
