config.yaml :

telegram_token: "5327342:GVJsadjgvwequJHSAGh"

alertmanager config:

  - alert: OutOfDiskSpace
    expr: node_filesystem_free_bytes / node_filesystem_size_bytes * 100 < 10
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: "Out of disk space (instance {{ $labels.instance }})"
      description: "Disk is almost running out of available space (< 10% left)\n  VALUE = {{ $value | humanize }}\n  LABELS: {{ $labels }}"

The problem with description - (< 10% left) , special symbols can not be parsed.

P.S. I am not a programmer and i dunno how to fix it, so i can't make a PR, sry.

may be you should use < instead of \u003c

hi, @antonrubtsov ! I should use human readable format in my alertmanager config like this description: "Disk is almost running out of available space (< 10% left) and i believe it should be parsed in code.
