Grafan report for SLA using blackbox exporter and prometheus

[Ani Prabhakaran]

Hello Everyone,

   I have a requirement to show my system's up time as a report, so for that I am using Blackbox exporter, Prometheus and Grafana.

   Till now I was showing my system's up time in percentage  for specific time range using Grafana with following expression

   avg_over_time(probe_success{instance="myhost-url",job="blackbox-http",module="http_2xx"}[7d]) * 100"

   Now there is a new requirement, were I have to show Up time percentage of my system per day for a week (including current day). 

To put it in visualized form ,report has to be like bar graph, each bar graph represent percentage of system up time for a day, so when showing report for week, there will be 7 bar, one per day

The Y- axis represent up time percentage % , while X-axis represent the date (for last 7 day including current date).

Is this possible to represent this bar graph in Grafana, if yes would like to hear from you guys.

Thanks in advance.

Ani.
