We don't have anything like that currently. That's why you need to be really careful with external services.
It's not a solution, but it can help mitigate the problem. I use https://betterstack.com to monitor external services, including Traccar itself. When they don't respond for some reason, it alerts you, and you can quickly address the issue by finding a manual solution, such as disabling the services in the XML file and restarting Traccar.
I previously used the self-hosted service Nominatim. Now, I'm hosting Traccar Geocoder on 1 virtual CPU, 512 MB of memory, and 10 GB of disk space, and it's been running without any issues for a month. I installed it locally first and then migrated it to the VPS. Previously, Nominatim's self-hosted service cost $6 per month, but now it's only $4/month; both are VPS servers hosted by Digital Ocean.
Greetings, I have a performance question. When I use external geocoders and Overpass, and for some reason they fail, there's a delay in the system updates for my devices. This is understandable, of course; they start to lag, and the log begins to fill up with WARNING messages. Now, my question is, is there a way to use these services and set a limiter in the configuration so that if it doesn't find a response, it stops using them for a while? Is there a configuration key like that? Thanks.
