How are you running loki? Straight from the exe or in docker?
just installed loki locally on my windows computer(same as grafana runs on), and i cannot "save and test".
Straight from exe. I don’t use docker at all.
C:\Program Files\GrafanaLabs!Loki\loki-windows-amd64.exe --config.file=loki-config.yaml
What does it show when you run it in commamd line
Please post screen shot?
http://localhost:3100/metrics ← this page works, btw.
- now in the above folder, do you see a tmp folder?
- Aso go to http://localhost:3100/metrics and do you see some results?
Content of the tmp folder:
screenshot of metrics:
Btw, the content of the following file is actually from the logfile on a remote server via promtail, so its actually connected …wow… C:\Program Files\GrafanaLabs!Loki\tmp\loki\wal\00000000
Also, right before i created this post, i deleted the whole tmp folder, and it populated it.
and following section of you loki config file, what does yours show?
chunks_directory: ./tmp/loki/chunks rules_directory: ./tmp/loki/rules
My loki conf:
#LOKI conf auth_enabled: false server: http_listen_port: 3100 #log_level: debug grpc_listen_port: 9096 common: path_prefix: ./tmp/loki/ storage: filesystem: chunks_directory: ./tmp/loki/chunks rules_directory: ./tmp/loki/rules replication_factor: 1 ring: instance_addr: 127.0.0.1 kvstore: store: inmemory #query_range: # results_cache: # cache: # embedded_cache: # enabled: true # distributed: false # max_size_mb: 100 schema_config: configs: - from: 2020-10-24 store: boltdb-shipper object_store: filesystem schema: v11 index: prefix: index_ period: 24h ruler: alertmanager_url: http://localhost:9093 # By default, Loki will send anonymous, but uniquely-identifiable usage and configuration # analytics to Grafana Labs.

Btw, dont have any alertmanager setup yet.
so in grafana you entered https here we see it works on http
You have good eyes! i tried both HTTP and HTTPS, but i found out that i got the 404 on HTTP, so i understood that i had to use HTTP.
Sorry for the missleading screenshot above.
I got the same error in grafana using HTTP.
no lets move on to possibly networking issues
is grafana on same server as loki?
what does this mean?
Grafana is running on my pc, same as loki. Promtail is installed on an remote server.
Regarding my conclusion: when i press “save & test”, something happens in the loki logs. The 5 lines of loki log i pasted above comes from grafana since i pressed that button. The five lines comes each time i press the button. → just installed loki locally on my windows computer(same as grafana runs on), and i cannot "save and test". - #3 by patchie
I also know that loki connects to promtail, since it fetches data from the remote server. → just installed loki locally on my windows computer(same as grafana runs on), and i cannot "save and test". - #9 by patchie
I can also add that on the same remote server running promtail, i have also “windows_exporter” installed on that server. windows_exporter sends data to prometheus(local pc, same as loki and grafana).
Just because you see folders in loki does not necessarily mean things are working. You have to do actual tests.
I think the above is where your issue is. Notice what doco says about Promtail
Promtail is an agent which ships the contents of local logs to a private Grafana Loki instance or Grafana Cloud. It is usually deployed to every machine that has applications needed to be monitored.
It is a push system. Cause I do not see anything in your Loki config, I have know to be blind often, that points to Promtail.
Let’s see your promtail config please.
in the following folder, i found files with actual log data from the server, so thats why i know it fetches data: C:\Program Files\GrafanaLabs!Loki\tmp\loki\wal\00000000
yep, the graphics you posted seems fair. I have grafana and loki on same pc, and promtail on another server.
#promtail config server: http_listen_port: 9080 grpc_listen_port: 0 positions: filename: C:\Users\****\AppData\Local\Temp\positions.yaml clients: - url: http://*********:3100/loki/api/v1/push # The URL where Loki is listening, denoted in Loki as http_listen_address and # http_listen_port. If Loki is running in microservices mode, this is the HTTP # URL for the Distributor. Path to the push API needs to be included. # Example: http://example.com:3100/loki/api/v1/push scrape_configs: - job_name: *******-Logs static_configs: # Configures the discovery to look on the current machine. # This is required by the prometheus service discovery code but doesn't # really apply to Promtail which can ONLY look at files on the local machine # As such it should only have the value of localhost, OR it can be excluded # entirely and a default value of localhost will be applied by Promtail. - targets: - localhost labels: job: varlogs # The path to load logs from. Can use glob patterns (e.g., /var/log/*.log). __path__: F:\*********\standalone\log\*.log # Additional labels to assign to the logs # [ <labelname>: <labelvalue> ... ]
I am out of ideas.
But hey Yosiasz, thanks so much for your time and effort to try to help me!
I now upgraded to last version:
Loki: 2.7.0 (https://github.com/grafana/loki/releases/download/v2.7.0/loki-windows-amd64.exe.zip)
Promtail: 2.7.0 (https://github.com/grafana/loki/releases/download/v2.7.0/promtail-windows-amd64.exe.zip)
Still doesn’t work.
What if you use the actual ip of pc or 127.0.0.1 in grafana loki connection
Tried with ip, but no difference. hmm
