TAPSET::JSON(3stap) TAPSET::JSON(3stap)
tapset::json - systemtap json tapset
The JSON tapset provides probes, functions, and macros to
generate
a JSON metadata and data file. The JSON metadata file is located
in
/proc/systemtap/MODULE/metadata.json. The JSON data file is
located
in /proc/systemtap/MODULE/data.json. The JSON data file is
updated
with current data every time the file is read.
json_set_prefix
Set the metric prefix.
See function::json_set_prefix(3stap)
for details.
json_add_numeric_metric
Add a numeric metric
See function::json_add_numeric_metric(3stap)
for details.
json_add_string_metric
Add a string metric
See function::json_add_string_metric(3stap)
for details.
json_add_array
Add an array
See function::json_add_array(3stap)
for details.
json_add_array_numeric_metric
