Hi Daniel,
thanks for ur reply.
This is telegraf config file, the same configuration working for server1 and its not working for server2…!! weird.
[global_tags]
dc = “server2”
[agent]
interval = “10s”
round_interval = true
metric_buffer_limit = 1000
flush_buffer_when_full = true
collection_jitter = “0s”
flush_interval = “10s”
flush_jitter = “0s”
debug = true
quiet = false
logfile = “/var/log/telegraf/telegraf.log”
hostname = “”
[[inputs.logparser]]
files = [“/var/log/tomcat/app.log”]
from_beginning = false
name_override = “project_info”
[inputs.logparser.grok]
patterns = [“%{MAINJAVACLASS:class:tag}: %{GREEDYDATA:block}”]
custom_patterns = ‘’’
MAINJAVACLASS (?:[a-zA-Z0-9-]+.)+[A-Za-z0-9$]+
‘’’
[inputs.logparser.tags]
project_name = “server2”
[[outputs.influxdb]]
urls = [“http://x.x.x.x:8086”] # required
database = “db1” # required
precision = “s”
timeout = “5s”
I assume that the pattern isn’t matching the log file, can you post a few lines from the log?
Hi Daniel,
appreciate for your support.
This issue has fixed now, i’ve given rwx permission to others in that dir of app log. this resolves… 
thanks again.
Hi. I am also facing the same issue. Telegraf is not collecting metrics and I guess its not the permission issue as well. Because telegraf and user creating the file are in the same group.
Any working solution for this?
