Distribution of metrics per hour

Qloudstat offers a resolution of all metrics by day. To give you an idea how these are distributed over a given day we now additionally plot a graph of accumulated hits per hour to give you a better insight of access characteristics over the day.

Additionally you can now also display the timeline with a resolution of weeks or months if you want a more generic view of time data.

Monitoring with threshold alerts

We are constantly working on the feature set of Qloudstat and today we are introducing new monitoring capabilities that are very useful when you need to track the usage of resources served by Amazon S3 or a CDN.

Qloudstat now allows to configure alerts for a given lower or upper threshold triggered by a dimension and metric. Optionally a filter for the dimension value can be set. Once the threshold for the given period is reached you will get notified by email. The next alert will only be sent again after the period has been elapsed. The accumulation for the configured dimension and metric is reset after each period.

Monitoring threshold with alerts


Consider the following usage scenarios where this becomes very useful:

  • Alert when the cost per month reaches a certain limit imposed for a country.
  • Get an alert for 404 HTTP error codes to get notified as soon as possible when you tried to serve a broken link.
  • Get notified when a file is no more downloaded with a lower limit and a filter for the URI dimension.

There is no limit for the number of alerts and they can be configured for daily, weekly or monthly periods.


Filtering dimension values

Qloudstat allows you to draw quick conclusions about individual dimension values (such as a single resource in your container) by selecting an entry in the value result list. We now also allow to filter these table results with a custom input supporting the ? and * glob patterns to match dimension values that fit the input pattern.

Glob Pattern for URIs

To give an example consider you want to have the metrics for all files that are stored in a container with a given prefix or suffix only. Navigate to the URI dimension analytics page of your report and enter a glob pattern such as */5902/*.png to only list URIs that contain this pattern in their path. This is quite useful to filter versioned resources or limit the result list to files that are served from a specific location in your bucket or CDN origin.

The dimension values list supports multi-selection which gives you a simple way to bring the selected values in relation. When selecting multiple values a pie chart next to the table shows up with the percentage of each value compared to all selected ones.

Update: The filter with search patterns now also works for enumerated dimension values such as HTTP status code.
