No Unique Label

[rider8581]

I am pushing logs to loki and it is working nice.
But when I show the log in Grafana, it is saying "no unique labels"
Could you guide me how I can set the unique label?

The unique labels are a feature of Grafana, comparing the unique labels of your query results. To set labels with python-logging-loki use the tags option in the examples.
tags={"app_label": your_app_name_variable, "host": socket.gethostname()}

@MartijnVanAndel I'm confused about the use of tags and labels here. If you set tags, are these treated as loki Labels? and if so, isn't storing hostname as a label a label antipattern?

[MartijnVanAndel]

It's been quite some time I've been working with this. So don't know if some properties have changed over time. But at the time of writing in 2021 the following was the case:

• some of the labels of this package/loki have different names, compared to what grafana was expecting in it's default views, i.e. host vs hostname or log level/severity/verbose
• no setting was available to rename these labels
• tags in this package become indeed available as labels in Loki/grafana
• by using the tags feature in this package you could hack the required label names in the system

So I wouldn't say best practice, but it solved label name requirements without programming.
