Mac OS X Logs
You can configure your Mac OS X to send system to logs to Loggly. We use fluentd to send the OS X system log over our HTTP/S endpoint. This is because OS X has an older syslog daemon that does not support the newer RFC 5424 format that Loggly requires. For alternatives, please see the Advanced Options section.
- Run the Configure Mac script
Run our automatic configure-mac script below to setup Mac OS X logging and send the logs to Loggly through your fluentd. Alternatively, you can follow our manual configuration instructions below.
curl -O https://www.loggly.com/install/configure-mac.sh sudo bash configure-mac.sh -a SUBDOMAIN -u USERNAME
- SUBDOMAIN: your account subdomain that you created when you signed up for Loggly
- USERNAME: your Loggly username, which is visible at the top right of the Loggly console
You will need to enter your system root password so it can update your fluentd configuration. It will then prompt for your Loggly password.
Search Loggly for events with the Mac tag over the past hour. It may take a few minutes to index the event. If it doesn’t work, see the troubleshooting section below.
- Install xcode command line tools
- Install Fluentd
- Install Loggly Plugin for Fluentd
- Configure Fluentd
If you haven’t already, install xcode command line tools.
Install Fluentd using following command.
sudo gem install fluentd --no-ri --no-rdoc -n/usr/local/bin
Install the Loggly output plugin for the Fluentd using following command.
sudo gem install fluent-plugin-loggly
Open or create a new configuration file for fluentd. You can store this in your home directory or elsewhere.
sudo vim fluentd-loggly.conf
Paste the following configuration into the file.
<source> type tail format none path /var/log/system.log tag system_logs </source> <match **> type loggly loggly_url http://logs-01.loggly.com/inputs/TOKEN/tag/Mac </match>
- TOKEN: your customer token from the source setup page
Now run the following command to send logs to Loggly.
fluentd -c fluentd-loggly.conf
Search Loggly for events with the Mac tag over the past 20 minutes. It may take a few minutes to index the event. If it doesn’t work, see the troubleshooting section below.

Troubleshooting Mac OS Logs
If you don’t see any data show up in the verification step, then check for these common problems.
- Wait a few minutes in case indexing needs to catch up
- Check to see if the fluentd-loggly.conf is properly created and placed in the proper location. It should be in the /home/Fluentd folder.
- Check to see if the path for the system.log file provided is correct. It should be /var/log/system.log.
- Run “sudo tcpdump dst logs-01.loggly.com and port 80″ to verify HTTP events are being sent to Loggly
- Search or post your own MacOS logging question in the community forum.
