Hello,
im on NixOs 24.05 and am followed this tutorial:
Enabled following logs for nextcloud:
services.nextcloud = {
settings = {
loglevel = 1;
log_type = "file";
};
};
Added the scrape_config to promtail:
{
job_name = "system";
static_configs = {
targets = [ "localhost" ];
labels = {
instance = "${builtins.toString config.services.nextcloud.hostName}";
env = "${builtins.toString config.networking.hostName}";
job = "nextcloud";
__path__ = "/tank/Nextcloud/data/{nextcloud,audit}.log";
};
};
}
however, nixos-rebuild throws an error: Failed to start Promtail log ingress.
And the logs show:
Sep 17 14:21:27 omhe promtail-pre-start[253583]: Unable to parse config: /nix/store/wk8w56rkkgj1j8wwmv138azh5xlrp3la-promtail-config.json: yaml: unmarshal errors:
Sep 17 14:21:27 omhe promtail-pre-start[253583]: line 31: cannot unmarshal !!map into discovery.StaticConfig. Use `-config.expand-env=true` flag if you want to expand environment variables in your config file
Sep 17 14:21:27 omhe systemd[1]: promtail.service: Control process exited, code=exited, status=1/FAILURE
so there seems to be some kind of error in the scrape_config. according to the tutorial, it should look like this:
scrape_configs: #The most important part
- job_name: system
static_configs:
- targets:
- localhost #Promtail target is localhost
labels:
instance: nextcloud.voidquark.com #Label identifier for instance (hostname -f)
env: home-lab #Environment label
job: nextcloud #Job label
__path__: /var/log/nextcloud/{nextcloud,audit}.log
I’m really not sure on how to change the promtail.configuration.scrape_configs to match the above.
Appreciate all input! thanks
