What did you expect to happen?
want to extract service logs from syslog using Promtail and Loki and visualize them in Grafana, organized by server. -
Can you copy/paste the configuration(s) that you are having problems with?
scrape_configs:- job_name: syslog
static_configs:- targets:
- localhost
labels:
job: syslog
host: “${HOSTNAME}”
path: /var/log/syslog
pipeline_stages:
- localhost
- regex:
expression: ‘^(?P[^ ]+ [^ ]+ [^ ]+) (?P[^ ]+) (?P[^]+)(?:[\d+])?: (?P.*)’ - match:
selector: ‘{host=“${HOSTNAME}”}’
stages:
- labels:
timestamp: “${timestamp}”
host: “${host}”
service: “${service}”
message: “${message}”
- targets:
- job_name: syslog
I have two query variables in Grafana, one for ‘host’ and another for ‘service’. I want to filter the ‘service’ variable based on the ‘host’ selected. Currently, all services from all hosts appear in the ‘service’ variable regardless of the selected host, but I want it to display services specific to the selected host.
