Kibana queries and filtersedit

This topic provides a short introduction to some useful queries for searching Packetbeat data. For a full description of the query syntax, see Searching Your Data in the Kibana User Guide.

In Kibana, you can filter transactions either by entering a search query or by clicking on elements within a visualization.

Create queriesedit

The search field on the Discover page provides a way to query a specific subset of transactions from the selected time frame. It allows boolean operators, wildcards, and field filtering. For example, if you want to find the HTTP redirects, you can search for type: http AND http.code: 302.

Kibana query

String queriesedit

A query may consist of one or more words or a phrase. A phrase is a group of words surrounded by double quotation marks, such as "test search".

To search for all HTTP requests initiated by Mozilla Web browser version 5.0:

"Mozilla/5.0"

To search for all the transactions that contain the following message:

"Cannot change the info of a user"
Note

To search for an exact string, you need to wrap the string in double quotation marks. Without quotation marks, the search in the example would match any documents containing one of the following words: "Cannot" OR "change" OR "the" OR "info" OR "a" OR "user".

To search for all transactions with the "chunked" encoding:

"Transfer-Encoding: chunked"

Field-based queriesedit

Kibana allows you to search specific fields.

To view HTTP transactions only:

type: http

To view failed transactions only:

status: Error

To view INSERT queries only:

method: INSERT

Regexp queriesedit

Kibana supports regular expression for filters and expressions. For example, to search for all HTTP responses with JSON as the returned value type:

http.response_headers.content_type: *json

See Elasticsearch regexp query for more details about the syntax.

Range queriesedit

Range queries allow a field to have values between the lower and upper bounds. The interval can include or exclude the bounds depending on the type of brackets that you use.

To search for slow transactions with a response time greater than or equal to 10ms:

responsetime: [10 TO *]

To search for slow transactions with a response time greater than 10ms:

responsetime: {10 TO *}

Boolean queriesedit

Boolean operators (AND, OR, NOT) allow combining multiple sub-queries through logic operators.

Note

Operators such as AND, OR, and NOT must be capitalized.

To search for all transactions except MySQL transactions:

NOT type: mysql

To search for all MySQL INSERT queries with errors:

method: INSERT AND mysql.iserror: true

Lucene also supports parentheses to group sub-queries.

To search for either INSERT or UPDATE queries with a response time greater than or equal to 30ms:

(method: INSERT OR method: UPDATE) AND responsetime: [30 TO *]

Create filtersedit

In Kibana, you can also filter transactions by clicking on elements within a visualization. For example, to filter for all the HTTP redirects that are coming from a specific IP and port, click the Filter for value ./images/filterforval_icon.png icon next to the client_ip and client_port fields in the transaction detail table. To exclude the HTTP redirects coming from the IP and port, click the Filter out value ./images/filteroutval_icon.png icon instead.

Filter from context

The selected filters appear under the search box.
