# Monitoring agent installation and configuration

When the monitoring agent is running, it looks for buffered messages in the configured directory or a message queuing system and forwards them. To forward buffered messages from the MLOps library to DataRobot MLOps, install and configure the monitoring agent as indicated below.

**Run on a host machine:**
Unpack the MLOps .tar file:
tar
-xvf
datarobot_mlops_package-*.tar.gz
Update the configuration file:
cd
datarobot_mlops_package-*
;
<your-favorite-editor>
./conf/mlops.agent.conf.yaml
Configure the monitoring agent:
In the agent configuration file,
conf\mlops.agent.conf.yaml
, you must update the values for
mlopsUrl
and
apiToken
. By default, the agent will use the
filesystem
channel. If you use the
filesystem
channel, make sure you create the spooler directory (by default, this is
/tmp/ta
).
Important
For the
filesystem
spooler channel, the
directory
path you provide
must
be an absolute path (containing the complete directory list) for the agent to access the
/tmp/ta
directory (or a custom directory you create).
If you want to use a different channel, follow the comments in the agent configuration file to update the path.

# Comment out and configure the lines below for the spooler type(s) you are using.

# Note: The filesystem spooler directory must be an absolute path to the "/tmp/ta" directory.
# Note: Spoolers must be set up before using them.
#       - For the filesystem spooler, create the directory that will be used.
#       - For the SQS spooler, create the queue.
#       - For the PubSub spooler, create the project and topic.
#       - For the Kafka spooler, create the topic.

**Run natively in Docker:**
To run the monitoring agent natively in Docker, first build the
datarobot/mlops-tracking-agent
image from the MLOps agent tarball:
make
build
-C
tools/agent_docker
Configure the monitoring agent in Docker, mounted to the default directory or a custom location:
To run the monitoring agent with the configuration mounted to the default directory:
docker
run
\
-v
/path/to/mlops.agent.conf.yaml:/opt/datarobot/mlops/agent/conf/mlops.agent.conf.yaml
\
datarobot/mlops-tracking-agent
To run the monitoring agent with the configuration mounted to a custom location:
docker
run
\
-v
/path/to/mlops.agent.conf.yaml:/var/tmp/mlops.agent.conf.yaml
\
-e
MLOPS_AGENT_CONFIG_YAML
=
/var/tmp/mlops.agent.conf.yaml
\
datarobot/mlops-tracking-agent


## Use the monitoring agent

Once the monitoring agent is configured, you can run the agent, check the agent status, and shut down the agent.

### Run the monitoring agent

Start the agent using the config file:

```
cd datarobot_mlops_package-*;
./bin/start-agent.sh
```

Alternatively, start the agent using environment variables:

```
export AGENT_CONFIG_YAML=<path/to/conf/mlops.agent.conf.yaml>
export AGENT_LOG_PROPERTIES=<path/to/conf/mlops.log4j2.properties>
export AGENT_JVM_OPT=-Xmx4G
export AGENT_JAR_PATH=<path/to/bin/mlops-agent-ver.jar>
./bin/start-agent.sh
```

For a complete reference of the available environment variables, see [MLOps agent environment variables](https://docs.datarobot.com/en/docs/classic-ui/mlops/deployment/mlops-agent/monitoring-agent/env-var.html).

### Check the agent's status

To check the agent's status:

```
# Check status
./bin/status-agent.sh
```

```
# Check status with real-time resource usage
./bin/status-agent.sh --verbose
```

### Shut down the agent

To shut down the agent:

```
./bin/stop-agent.sh
```
