## Introduction
I know! You cannot simply replace Google Analytics with parsing access logs and displaying a couple of charts. But to be honest, I actually never used Google Analytics to the fullest extent and was usually interested in seeing page hits and which pages were visited most often.
I recently moved my blog from Firebase to a VPS and also decided to remove Google Analytics tracking code from the site since its quite malicious and tracks users across other pages also and is creating a profile of a user, and I've had it. But I also need some insight of what is happening on a server and which content is being read the most etc.
I have looked at many existing solutions like:
- [Umami](https://umami.is/)
- [Freshlytics](https://github.com/sheshbabu/freshlytics)
- [Matomo](https://matomo.org/)
But the more I looked at them the more I noticed that I am replacing one evil with another one. Don't get me wrong. Some of these solutions are absolutely fantastic but would require installation of databases and something like PHP or Node. And I was not ready to put those things on my fresh server. Also having Docker installed is out of the question.
## Opting for log parsing
So, I defaulted to parsing already existing logs and generating HTML reports from this data.
I found this amazing software [GoAccess](https://goaccess.io/) which provides all the functionalities I need, and it's a single binary. Written in Go.
GoAccess can be used in two different modes.
Running in a terminal
Running in a browser
I, however, need this to run in a browser. So, the second option is the way to go. The Idea is to periodically run cronjob and export this report into a folder that gets then server by Nginx behind a Basic authentication.
## Getting Nginx ready
I choose Ubuntu on [DigitalOcean](https://www.digitalocean.com/). First I installed [Nginx](https://nginx.org/en/), and [Letsencrypt](https://letsencrypt.org/getting-started/) certbot and all the necessary dependencies.
```sh
# log in as root user
sudo su -
# first let's update the system
apt update && apt upgrade -y
# let's install
apt install nginx certbot python3-certbot-nginx apache2-utils
```
After all this is installed we can create a new configuration for a statistics. Stats will be available at `stats.domain.com`.
```sh
# creates directory where html will be hosted
mkdir -p /var/www/html/stats.domain.com
cp /etc/nginx/sites-available/default /etc/nginx/sites-available/stats.domain.com
nano /etc/nginx/sites-available/stats.domain.com
```
```nginx
server {
root /var/www/html/stats.domain.com;
server_name stats.domain.com;
index index.html;
location / {
try_files $uri $uri/ =404;
}
}
```
Now we check if the configuration is ok. We can do this with `nginx -t`. If all is ok, we can restart Nginx with `service nginx restart`.
After all that you should add A record for this domain that points to IP of a droplet.
Before enabling SSL you should test if DNS records have propagated with `curl stats.domain.com`.
Now, it's time to provision TLS certificate. To achieve this, you execute command `certbot --nginx`. Follow the wizard and when you are asked about redirection always choose 2 (always redirect to HTTPS).
When this is done you can visit https://stats.domain.com and you should get 404 not found error which is correct.
## Getting GoAccess ready
If you are using Debian like system GoAccess should be available in repository. Otherwise refer to the official website.
```sh
apt install goaccess
```
To enable Geo location we also need one additiona thing.
```sh
cd /var/www/html/stats.stats.com
wget https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-City.mmdb
```
Now we create a shell script that will be executed every 10 minutes.
```sh
nano /var/www/html/stats.domain.com/generate-stats.sh
```
Contents of this file should look like this.
```sh
#!/bin/sh
zcat -f /var/log/nginx/access.log* > /var/log/nginx/access-all.log
goaccess \
--log-file=/var/log/nginx/access-all.log \
--log-format=COMBINED \
--exclude-ip=0.0.0.0 \
--geoip-database=/var/www/html/stats.domain.com/GeoLite2-City.mmdb \
--ignore-crawlers \
--real-os \
--output=/var/www/html/stats.domain.com/index.html
rm /var/log/nginx/access-all.log
```
Because after a while nginx creates multiple files with access logs we use [`zcat`](https://linux.die.net/man/1/zcat) to extract Gziped contents and create a file that has all the access logs. After this file is used we delete it.
If you want to exclude your home IP's result look at the `--exclude-ip` option in script and instead of `0.0.0.0` add your own home IP address. You can find your home IP by executing `curl ifconfig.me` from your local machine and NOT from the droplet.
Test the script by executing `sh /var/www/html/stats.domain.com/generate-stats.sh` and then checking `https://stats.domain.com`. If you can see stats instead of 404 than you are set.
It's time to add this script to cron with `cron -e`.
```go
*/10 * * * * sh /var/www/html/stats.domain.com/generate-stats.sh
```
## Securing with Basic authentication
You probably don't want stats to be publicly available, so we should create a user and a password for Basic authentication.
First we create a password for a user `stats` with `htpasswd -c /etc/nginx/.htpasswd stats`.
Now we update config file with `nano /etc/nginx/sites-available/stats.domain.com`. You probably noticed that the file looks a bit different from before. This is because `certbot` added additional rules for SSL.
Your location portion the config file should now look like. You should add `auth_basic` and `auth_basic_user_file` lines to the file.
```nginx
location / {
try_files $uri $uri/ =404;
auth_basic "Private Property";
auth_basic_user_file /etc/nginx/.htpasswd;
}
```
Test if config is still ok with `nginx -t` and if it is you can restart Nginx with `service nginx restart`.
If you now visit `https://stats.domain.com` you should be prompted for username and password. If not, try reopening your browser.
That is all. You now have analytics for your server that gets refreshed every 10 minutes.
