Greetings,
I am using crowdsec H2 db.
I am not able to find mysql bouncer so it can read mysql logs and do its magic.
Or I am mistaking this should not be bouncer?
Please advice
Hello,
I think you have confused some of the terms 
A bouncer is a component that will apply a decision (for example, ban this IP for 4h).
If I understand you, you want the mysql collection (CrowdSec Hub) to detect bruteforce attacks against mysql.
You can install it by running cscli collections install crowdsecurity/mysql on the machine where crowdsec is running.
You will also need to update crowdsec acquisition config (in /etc/crowdsec/acquis.yaml) to tell crowdsec to read your mysql logs (there is an example config in the link above).
Finally, you will also want to install a bouncer, in your case i’d recommend the firewall bouncer (Firewall Bouncer | CrowdSec) to block IPs that are trying to attack your mysql.
And I’m not sure what you mean by I am using crowdsec H2 db., are you talking about the metabase dashboard ?
