## Ubuntu Settings

### View IP Address
```
$ ip addr show ens33 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'
```

### Set static IP address

### PM2 Commands (Process manager running python scripts)

PM2 is already set up to run scripts against Cisco's [DevNet 12.5 Collaboration Sandbox](https://devnetsandbox.cisco.com/). You'll need to delete all the processes and add new ones for your IP addresses. I created an Excel spreadsheet to help create the command lines for this step. The Jabber Registration example is below. All example are set to run every 5 minutes.

[Excel Helper](https://github.com/sieteunoseis/cucm_tig_dashboard_ubuntu/blob/master/PM2_Helper.xlsx)

```
$ pm2 [list|ls|status]
$ pm2 flush
$ pm2 log
$ pm2 restart app_name
$ pm2 reload app_name
$ pm2 stop app_name
$ pm2 delete app_name
$ pm2 start perfmon_arg.py --interpreter python3 --name thread --cron '*/5 * * * *' --no-autorestart -- -ip 10.10.20.1 10.10.20.2 -u administrator -p ciscopsdt -c 'Cisco CallManager'
$ pm2 start cisco_axl_jabber.py --interpreter python3 --name jabber_status --cron '*/5 * * * *' --no-autorestart -- -ip 10.10.20.1 -u administrator -p ciscopsdt -v 12.0
$ pm2 save or pm2 set pm2:autodump true
$ pm2 stop all
$ pm2 show <id|name>
$ pm2 startup
$ pm2 monit
```

### SFTP Configuration (This is already preconfigured)
```
$ sudo groupadd sftp
$ sudo nano /etc/ssh/sshd_config
```

Paste at bottom

```
Match group sftp
ChrootDirectory /
X11Forwarding no
AllowTcpForwarding no
```
Add user to group

```
$ sudo usermod -a -G dashadmin sftp
```

## InfluxDB Settings

InfluxDB is already configured with sample data in it from Cisco's [DevNet 12.5 Collaboration Sandbox](https://devnetsandbox.cisco.com/).

```
$ sudo nano /etc/influxdb/influxdb.conf
$ influx -precision rfc3339
> show databases
> CREATE DATABASE cisco_perfmon WITH DURATION 90d
> use cisco_perfmon
> show measurements
> CREATE DATABASE cisco_risport WITH DURATION 90d
> use cisco_risport
> show measurements
```
If you'd like to remove the data and start fresh do the following:

```
$ influx -precision rfc3339
> drop database cisco_perfmon
> CREATE DATABASE cisco_perfmon WITH DURATION 90d
> drop database cisco_risport
> CREATE DATABASE cisco_risport WITH DURATION 90d
> drop database telegraf
> CREATE DATABASE telegraf WITH DURATION 90d
```

## Telegraf Settings

Telegraf config needs to be edited with updated IP addresses. Telegraf is used to pull stats from CUCM via SNMP. This was done due to a bug in the Perfmon API.

[CSCvn19112](https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvn19112/?rfs=iqvred)

```
$ sudo nano /etc/telegraf/telegraf.conf
$ sudo service telegraf restart
$ telegraf -test -config /etc/telegraf/telegraf.conf
$ snmpwalk -c dashboardRO -v 2c 10.10.20.1 -m +CISCO-CCM-MIB 1.3.6.1.4.1.9.9.156
$ cd /usr/share/snmp/mibs
```

Majority of the telegraf configuration was from this guide:

## Grafana Settings

Using the default settings created during installation. If you'd like more customization check out:

https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-grafana-on-ubuntu-18-04

Nginx is also install if you want to create a reverse proxy to port 3000.

* [Grafana Config](https://grafana.com/tutorials/run-grafana-behind-a-proxy/#0)
* [NGINX Config](https://grafana.com/tutorials/run-grafana-behind-a-proxy/#1)

## Python Scripts

Scripts are in the /home/dashboard/development directory. They are pulled from the following:

* [Perfmon](https://github.com/sieteunoseis/cisco_perfmon_influxdb)
* [Jabber Risport](https://github.com/sieteunoseis/cisco_risport_influxdb)

Sample python scripts are running via PM2. You can do the following to list them:

```
$ pm2 list
```

## Giving Back

If you would like to support my work and the time I put in creating the code, you can click the image below to get me a coffee. I would really appreciate it (but is not required).
