[GitHub] incubator-metron pull request: METRON-132 Monit Integration
GitHub user nickwallen opened a pull request:
https://github.com/apache/incubator-metron/pull/118
METRON-132 Monit Integration
#### Changes
##### METRON-85
Addressed bug that caused Amazon EC2 deployment to always wait a fixed 5 minutes instead of continuing when the hosts are actually ready
##### METRON-132
Decouple Install and Start of System Components
- Decouples the installation of components from the starting of them. A component can be installed, but not started.
- Define which services need started as a property.
- Enables different deployments to start more or fewer services. A development platform can start no services by default, while an Amazon EC2 cluster can start all services.
- For example, to start only component related to YAF ingestion
```
services_to_start:
- mysql
- elasticsearch
- enrichment
- yaf-parser
- yaf
```
##### METRON-132
Monit Integration
- Leverages Monit as a process watchdog to manage sensors, topologies, and core services.
- Monit web interface exposed at http://hostname:2812 which can be used to start, stop, check status of any of the sensors or topologies.
- When monitoring is enabled (on by default) if a process dies, it will be restarted.
- Will not monitor a service that is not installed.
- Monit command line tools simplify the process of managing Metron components
For example, tired of the noise from your laptop fan when running Metron's 'single node vagrant'? This will quiet her down. Finally, peace and quiet!
```
monit stop all
```
Need to work on a single ingest feed?
```
monit start bro
monit start bro-parser
```
Getting cold and need some heat? Start everything.
```
monit start all
```
Groups have also been defined to make things simpler. For example, start all parser topologies.
```
monit -g parsers start
```
Start all components required to consume and enrich Bro data.
```
monit -g bro start
```
What is running?
```
monit summary
```
- The post-deployment report for Amazon-EC2 provides links to Monit's web interface.
```
ok: [localhost] => {
"Success": [
"Apache Metron deployed successfully",
" Metron @ http://ec2-52-39-143-62.us-west-2.compute.amazonaws.com:5000",
" Ambari @ http://ec2-52-39-4-93.us-west-2.compute.amazonaws.com:8080",
" Sensor Status @ http://ec2-52-39-4-93.us-west-2.compute.amazonaws.com:2812",
" Topology Status @ http://ec2-52-39-130-62.us-west-2.compute.amazonaws.com:2812",
"For additional information, see https://metron.incubator.apache.org/'"
]
}
```
#### Validation
##### Quick Dev Platform
- Deploy
- Open http://node1:2812
- Ensure that all of the following services are running and visible in the Monit web interface.
- mysql, elasticsearch, pcap-service, metron-ui
- yaf, snort, snort-logs, bro, pcap-replay
- yaf-parser, bro-parser, snort-parser, enrichment
- Login to node1 and validate the previous step by running `monit summary`
- Run `monit stop all`
- Ensure all services stopped on the host
##### Amazon EC2
- Deploy
- Open http://ec2-host:2812 across each of the 10 nodes.
- Ensure that all of the following services are running somewhere on the cluster.
- mysql, elasticsearch, pcap-service, metron-ui
- yaf, snort, snort-logs, bro, pcap-replay
- yaf-parser, bro-parser, snort-parser, enrichment
- Login to a host and validate the previous step by running `monit summary`
- Run `monit stop all` on the same host
- Ensure all services stopped on the host

@dlyle65535 Recent commits ensure that MySQL is left running when installed so that the `mysql_client` role will work. I then changed the 'start' functionality to first stop everything running (should only be mysql), then start just the defined services.

Since both "Quick Dev Platform" and "Full Dev Platform" use the same properties at `metron-deployment/inventory/full-dev-platform`, we cannot have each start different services. This would be possible, if we separate out the properties that each use.
As a side note, I think we need to revisit what lives in `metron-deployment/inventory`.

I had to create custom start/stop/status scripts for the Storm topologies because Monit cannot handle passing an argument to a script. Otherwise, I would have just used the ones we already have in `/usr/metron/[version]/bin`

Yeah, I thought that as soon as we needed to start separate services, we'd have to separate the inventories. Was just about to create a duplicate directory and decided against it.

Should references to ansible_host be changed to inventory_hostname? IIRC, ec2 discovered hostnames are internal which may cause a problem.

For a future PR, this might be a nice pattern to use to define which services to install. This would be in lieu of the various booleans that we use currently; `install_bro`, `install_elasticsearch`, etc. A list is more compact and intuitive.

Double-checked. The external host name is added to /etc/monit.conf as expected.
I believe this is due to how we have the Ansible/EC2 module configured; in the ec2.ini file. In there we tell it to use the external host name instead of the internal.

I had to change this code because we now need to start Elasticsearch, create the indices, stop Elasticsearch, then continue on. We can't create indices with ES off. There is a similar need when loading the Geo data in MySQL.

If you haven't already, I'd double check that the external hostname ends up in monit.conf. We could be advantaged by the fact that monit is listening everywhere regardless of what is in "use address".
