RabbitMQ - OpenTelemetry Collector

icon Thumbnail icon

The RabbitMQ app is a unified log app. Preconfigured dashboards provide insight into error logs. RabbitMQ logs are sent to Sumo Logic through OpenTelemetry filelog receiver.


Fields creation in Sumo Logic for RabbitMQ

Following are the Fields which will be created as part of RabbitMQ App install if not already present.

  • User configured. Specify the user-friendly cluster name which RabbitMQ belongs to.
  • sumo.datasource. Has fixed value of rabbitmq.


This section provides instructions for configuring log collection for RabbitMQ running on a non-Kubernetes environment for the Sumo Logic App for RabbitMQ. By default, RabbitMQ logs are stored in a log file.

Follow the instructions to set up log collection:

  1. Configure logging in RabbitMQ. RabbitMQ supports logging via the following methods: local text log files, syslog and stdout. RabbitMQ logs have six levels of verbosity: debug, info, warning, error, critical, none. For details please visit this page. For the dashboards to work properly, log level needs to be set to debug. Default log level is info. All logging settings are located in RabbitMQ.conf.
  2. Configure RabbitMQ to write log lines to a local file. By default, RabbitMQ logs are stored in /var/log/rabbitmq/rabbit@<hostname>.log. The default directory for log files is listed in the RabbitMQ.conf file. To configure the log output destination to a log file, use one of the following settings, either in the configuration file. Edit or create /etc/rabbitmq/rabbitmq.conf file config:
log.dir = /var/log/rabbitmq
log.file = rabbitmq.log
log.file.level = debug

Once the logs are configured to be written to a local file, follow the below steps to configure collection in Sumo Logic.

For Linux systems with ACL Support, the otelcol install process should have created the ACL grants necessary for the otelcol system user to access default log locations. You can verify the active ACL grants using the getfacl command. Install the ACL in your Linux environment, if not installed.

The required ACL may not be supported for some rare cases, for example, Linux OS Distro, which is officially not supported by Sumo Logic. In this case, you can run the following command to explicitly grant the permissions.

sudo setfacl -R -m d:u:otelcol-sumo:r-x,d:g:otelcol-sumo:r-x,u:otelcol-sumo:r-x,g:otelcol-sumo:r-x <PATH_TO_LOG_FILE>

Run the above command for all the log files in the directory that need to be ingested, which are not residing in the default location.

If Linux ACL Support is not available, traditional Unix-styled user and group permission must be modified. It should be sufficient to add the otelcol system user to the specific group that has access to the log files.

For Windows systems, log files which are collected should be accessible by the SYSTEM group. Use the following set of PowerShell commands if the SYSTEM group does not have access.

$NewAcl = Get-Acl -Path "<PATH_TO_LOG_FILE>"
# Set properties
$fileSystemRights = "ReadAndExecute"
$type = "Allow"
# Create new rule
$fileSystemAccessRuleArgumentList = $identity, $fileSystemRights, $type
$fileSystemAccessRule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $fileSystemAccessRuleArgumentList
# Apply new rule
Set-Acl -Path "<PATH_TO_LOG_FILE>" -AclObject $NewAcl

Collection configuration and app installation

As part of data collection setup and app installation, you can select the App from App Catalog and click on Install App. Follow the steps below.

Step 1: Set up Collector


If you want to use an existing OpenTelemetry Collector, you can skip this step by selecting the Use an existing Collector option.

To create a new Collector:

  1. Select the Add a new Collector option.
  2. Select the platform where you want to install the Sumo Logic OpenTelemetry Collector.

This will generate a command that you can execute in the machine environment you need to monitor. Once executed, it will install the Sumo Logic OpenTelemetry Collector.


Step 2: Configure integration

In this step, we will be configuring the yaml file required for RabbitMQ Collection. Path of the log file configured to capture RabbitMQ logs is needed to be given here.

The files are typically located in /var/log/rabbitmq/rabbit@<hostname>.log. You can add any custom fields which you want to tag along with the data ingested in sumo. Click on the Download YAML File button to get the yaml file.


Step 3: Send logs to Sumo Logic

Once you have downloaded the yaml file as described in the previous step, follow the below steps based on your platform.

  1. Copy the yaml file to /etc/otelcol-sumo/conf.d/ folder in the RabbitMQ instance which needs to be monitored.
  2. Restart the collector using:
  sudo systemctl restart otelcol-sumo

After successfully executing the above command, Sumo Logic will start receiving data from your host machine.

Click Next. This will install the app (dashboards and monitors) to your Sumo Logic Org.

Dashboard panels will start to fill automatically. It's important to note that each panel fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but within 20 minutes, you'll see full graphs and maps.

Sample log messages

Here's a sample log message you'd find in Non-Kubernetes environments.

2023-01-16 05:53:44.858 [info] <0.44.0> Application cowboy exited with reason: stopped

Sample queries

This sample Query is from the RabbitMQ - Logs dashboard > Events by Severity panel.

Query String
 %"sumo.datasource"="rabbitmq" %""=**
| json "log" as _rawlog nodrop
| if(isEmpty(_rawlog),_raw,_rawlog) as _raw
| parse "* * [*]" as date,time,severity | count by severity
