Empty graph and no query data


I’m trying to configure Telegraf+InfluxDB+Grafana. Telegraf works fine, sending the selected data to influx db. I can query it from influx shell. After that on Grafana configuration - my db is visible. Creating new dashboard graph allows me to pick my telegraf db and the hosts that send their perf.count. info to influxdb. But after that nothing happens. Here is a screen of it:

Any suggestions what do I miss?

Thank you in advance!
