Test Connectivity for Sumo Logic Collectors

Test your connectivity

Make sure you have the required access and connectivity to the Sumo Logic service by running these checks from the machine where you want the Collector installed.

Choose one of these testing options:

  • Telnet. Telnet session to collectors.sumologic.com 443 and you should see a result like this one:
$telnet collectors.sumologic.com 443
Trying collectors.sumologic.com...
Connected to prod-events-lb-1056629993.us-east-1.elb.amazonaws.com.
  • curl command. The fastest way to check your connectivity is to use a curl command to connect to the service. The "curl" tool is available in Windows in the "SSL enabled" form for testing.
$ curl -i https://collectors.sumologic.com
$ curl -i https://collectors.sumologic.com/rest/registry/ping
$  time nslookup collectors.sumologic.com

Troubleshoot common firewall issues

If your results show a connection failure, it can be a firewall issue.

  • Check your firewall settings to verify that connectivity is allowed for collection endpoints. Refer to Sumo Logic Endpoints for firewall-related suggestions.
  • For Windows firewalls, you can create an outbound rule to allow outbound Collector connections, and try again.

To create a new outbound rule for the Windows firewall:

  1. Go to Administrative Tools > Firewall Settings.
  2. Click New Rule.
  3. Select Port for the type of rule, and then click Next.
  4. Enter 443 for the port, and then click Next.
  5. Select Allow for the connection and then click Next.
  6. Select the appropriate Profile for your environment, but we recommend you leave all three options checked:
    • Domain
    • Public
    • Private
  7. Click Next.
  8. Enter a name and a description for your new rule, and then click Finish.
