Break down requests by status code

Console

• An Azion account. To create one, refer to Create an account.
• An application served by a workload, with requests in the range you want to read.
• Access to Azion Console. To sign in, refer to How to access Azion Console.

API

• An Azion account. To create one, refer to Create an account.
• An application served by a workload, with requests in the range you want to read.
• A personal token. To create one, refer to How to manage a personal token.
• curl.

Console

To open the breakdown in Azion Console:

The dashboard shows four line charts, HTTP Status Codes 2XX to HTTP Status Codes 5XX, and the Requests by Status and Upstream Status table. Each legend entry totals one series over the range, which starts at Last 5 minutes. To read a longer period, refer to Filters and time range.

API

To read the breakdown with the GraphQL API, send a POST request to https://api.azion.com/v4/metrics/graphql. The query sums requests and groups the sums by status.

Replace [TOKEN VALUE] with your personal token, and the begin and end values with your range:

The API answers 200 with one row per status code, the most frequent first:

The sum values of all rows add up to the requestsTotal of the range. limit: 100 keeps every code: without limit, the API returns 10 rows. For every field of the dataset, refer to Real-Time Metrics GraphQL fields.

Console

To filter the dashboard in Azion Console:

A chip under the filter row reads Status between: (500,599). The Requests by Status and Upstream Status table now lists only the pairs whose status is in that range, so a server error is no longer hidden behind the most frequent 200 responses.

API

To filter with the API, add statusRange to filter, next to tsRange:

The API answers 200 with the 5XX codes alone:

To total a class, sum requests with statusRange, as above. requestsStatusCode5xx can return less for the same range, because it counts only the 5XX codes that have no field of their own. For each class field, refer to Build dashboards.

Console

To narrow the 5XX responses to one host in Azion Console, keep the Status filter and add a second one:

A second chip reads Host equals: www.example.com. The HTTP Status Codes 5XX chart and the table now count only the 5XX responses of that host. To check another host, select the Host chip and change its value.

API

To rank the hosts with the API, keep statusRange and group by host instead of status:

The API answers 200 with the hosts that returned 5XX responses, the most errors first:

limit: 10 keeps the ten hosts with the most errors.

Console

In Azion Console, keep the Status filter and read the Requests by Status and Upstream Status table. Each row pairs a Status with an Upstream Status, and Total counts the requests with that pair. The table lists the 10 most frequent pairs.

API

To pair the two codes with the API, group by status and upstreamStatus. The query keeps the 5XX filter and the ten most frequent pairs, as the Console table does:

The API answers 200 with one row per pair:

A row whose upstreamStatus equals status counts errors that the origin returned. One status code can appear in several rows, once per upstream status.
