Install the Apache App, Monitors, and View the Dashboards

The Sumo Logic Application for Apache consists of predefined searches and Dashboards, providing visibility into your environment for real-time or historical analysis.

This page provides instructions for installing the Sumo Logic Monitors for Apache, the app and descriptions of each of the app dashboards. These instructions assume you have already set up collection as described in the Collect Logs and Metrics for Apache page.

Install Monitors

Sumo Logic has provided out of the box alerts available through Sumo Logic monitors to help you proactively monitor your Apache Web servers and farms. These monitors are built based on metrics and logs datasets and include pre-set thresholds based on industry best practices and recommendations.

For details about individual alerts,  please see this page.

  • To install these alerts, you need to have the Manage Monitors role capability.

You can install monitors by importing a JSON file or using a Terraform script.

Method 1: Install Monitors by importing a JSON file:

  1. Download the JSON file that describes the monitors. 

  2. In the json file, replace $$apache_data_source with a custom source filter like webserver_farm=dev-apache for setting up alerts for a specific web server farm. If you want to configure this for all your web server farms you can find and replace $$apache_data_source with blank “”.

  3. Go to Manage Data > Alerts > Monitors.

  4. Click Add:

  1. Click Import and then copy paste the above JSON to import monitors. Name will be the folder name.

Method 2: Install the alerts using a Terraform script

Step 1: Generate a Sumo Logic access key and ID

Generate an access key and access ID for a user that has the Manage Monitors role capability in Sumo Logic using these instructions. Please identify which deployment your Sumo Logic account is in, using this link.

Step 2: Download and install Terraform 0.13 or later 

Step 3: Download the Sumo Logic Terraform package for Apache alerts

The alerts package is available in the Sumo Logic github repository. You can either download it through the “git clone” command or as a zip file. 

Step 4: Alert Configuration 

After the package has been extracted, navigate to the package directory terraform-sumologic-sumo-logic-monitor/monitor_packages/apache/

Edit the file and add the Sumo Logic Access Key, Access Id and Deployment from Step 1 .

access_id   = "<SUMOLOGIC ACCESS ID>"

access_key  = "<SUMOLOGIC ACCESS KEY>"

environment = "<SUMOLOGIC DEPLOYMENT>"

The Terraform script installs the alerts without any scope filters, if you would like to restrict the alerts to specific web server farm or environments, update the variable ’apache_data_source’. Custom filter examples: 

  1. A specific web server farm ‘’

  2. All web server farms in an environment ‘environment=prod’

  1. For alerts applicable to all web server farms that start with apache-prod, your custom filter would be: ‘webserver_farm=apache-prod*

  2. For alerts applicable to a specific web server farm within a production environment, your custom filter would be: 

‘webserver_farm=apache-1 and environment=prod (This assumes you have set the optional environment tag while configuring collection)

All monitors are disabled by default on installation, if you would like to enable all the monitors, set the parameter monitors_disabled to false in file.

By default, the monitors are configured in a monitor folder called “Apache”, if you would like to change the name of the folder, update the monitor folder name in “folder” key at file.

If you would like the alerts to send email or connection notifications, configure these in the file For configuration examples, refer to the next section.

Step 5: Email and Connection Notification Configuration Examples

Modify the file and populate connection_notifications and email_notifications as per below examples.

Pagerduty Connection Example:
connection_notifications = [
      connection_type       = "PagerDuty",
      connection_id         = "<CONNECTION_ID>",
      payload_override      = "{\"service_key\": \"your_pagerduty_api_integration_key\",\"event_type\": \"trigger\",\"description\": \"Alert: Triggered {{TriggerType}} for Monitor {{Name}}\",\"client\": \"Sumo Logic\",\"client_url\": \"{{QueryUrl}}\"}",
      run_for_trigger_types = ["Critical", "ResolvedCritical"]
      connection_type       = "Webhook",
      connection_id         = "<CONNECTION_ID>",
      payload_override      = "",
      run_for_trigger_types = ["Critical", "ResolvedCritical"]

Replace <CONNECTION_ID> with the connection id of the webhook connection. The webhook connection id can be retrieved by calling the Monitors API.

For overriding payload for different connection types, refer to this document.

Email Notifications Example:
email_notifications = [
      connection_type       = "Email",
      recipients            = [""],
      subject               = "Monitor Alert: {{TriggerType}} on {{Name}}",
      time_zone             = "PST",
      message_body          = "Triggered {{TriggerType}} Alert on {{Name}}: {{QueryURL}}",
      run_for_trigger_types = ["Critical", "ResolvedCritical"]

Step 6: Install the Alerts

  1. Navigate to the package directory terraform-sumologic-sumo-logic-monitor/monitor_packages/apache/ and run terraform init. This will initialize Terraform and will download the required components.
  2. Run terraform plan to view the monitors which will be created/modified by Terraform.
  3. Run terraform apply.

Step 7: Post Installation

If you haven’t enabled alerts and/or configured notifications through the Terraform procedure outlined above, we highly recommend enabling alerts of interest and configuring each enabled alert to send notifications to other users or services. This is detailed in Step 4 of this document.

Install the app

Now that you have set up logs and metric collections for Apache, you can install the Sumo Logic App for Apache to use the pre-configured Searches and Dashboards.

To install the app, do the following:

Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.

  1. From the App Catalog, search for and select the app. 

  2. Select the version of the service you're using and click Add to Library.

  1. To install the app, complete the following fields.

    1. App Name. You can retain the existing name, or enter a name of your choice for the app.

    2. Data Source. 
Choose Enter a Custom Data Filter, and enter a custom filter. Examples

      • For all Apache web server farms: 
        webserver_system=apache webserver_farm=*

      • For a specific web server farm:

    3. Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.

  2. Click Add to Library.

Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization. 

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

Filter with template variables   

Template variables provide dynamic dashboards that can rescope data on the fly. As you apply variables to troubleshoot through your dashboard, you view dynamic changes to the data for a quicker resolution to the root cause. For more information, see the Filter with template variables help page.
