Install Log Parsing Sensors

Access Logs Based Instrumentation

i. Pre-requisites

  • Satellite has been successfully installed.
  • You have noted down the Satellite's hostname:port or ip-address:port information.
  • The Satellite is reachable (via HTTP/s) from the location where you are going to install the log-parser.

ii. Pick an Application Name

Auto discovered API endpoints and their OpenAPI specifications are shown in the API Catalog, grouped under an application name. The application name helps segregate and group API endpoints from different environments, similar to how file folders work in an operating system.

Pick a descriptive name which will be used in the subsequent step below. For example: my-test-app.

iii. Follow instructions for your platform

Follow instructions for your specific platform/method below:

Install on Linux host via Docker


  • Docker Engine version 18.03.0 and above

1. Install Log Parser

If you are installing the Satellite and Log Parser on the same Linux host, please do NOT use localhost as the hostname below. Use the Linux host's IP address, or domain name instead. This is required as the Log Parser runs inside a Docker container, and localhost resolves to the Log Parser container's IP address, instead of the Linux host.

# Replace '<SATELLITE_URL>' with the values you noted down from the Satellite install
# Specify below the 'APP_NAME'. Do not quote the 'APP_NAME'.
# Environment Name is optional. If not specified, it defaults to 'staging'
docker run --rm -d --name=log-parser \
-v ./logs:/mnt/levo/logs \


  • The default address for the satellite in Docker-based Log Parser installations is
  • In case of levo hosted satellite, it is necessary that you must also specify an organization ID (LEVOAI_ORG_ID).
  • If you wish, you may also host the Satellite yourself and specify the address of the satellite to direct the Log Parser's data to it.

2. Verify connectivity with Satellite

Execute the following command to check for connectivity health:

# Please specify the actual container name for log-parser below
docker logs log-parser | grep "starting fluentd"

If connectivity is healthy, you should see output similar to below.

2024-02-22 01:27:06 +0000 [info]: starting fluentd-1.16.3 pid=7 ruby="3.2.2"
2024-02-22 01:27:06 +0000 [info]: #0 starting fluentd worker pid=16 ppid=7 worker=0
2024-02-22 01:27:06.831947051 +0000 {"pid":16,"ppid":7,"worker":0,"message":"starting fluentd worker pid=16 ppid=7 worker=0"}

Please proceed to the next step, if there are no errors.
