mod_measure_process: Report the enforced limit
The soft limit is what the kernel actually enforces, while the hard
limit is is how far you can change the soft limit without privileges.
Unless the process dynamically adjusts the soft limit, knowing the hard
limit is not as useful as knowing the soft limit.
Reporting the soft limit and the number of in-use FDs allows placing
alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

# Introduction ::: {.alert .alert-danger} Consider using [mod_mam][doc:modules:mod_mam] together with [mod_readonly] instead. ::: This module logs messages to a SQL database. SQL connection options are configured in a `message_log_sql` option, which has the same syntax as the `sql` option for [mod_storage_sql][doc:modules:mod_storage_sql]. # Usage You will need to create the following table in the configured database: ``` sql CREATE TABLE `prosodyarchive` ( `host` TEXT, `user` TEXT, `store` TEXT, `id` INTEGER PRIMARY KEY AUTOINCREMENT, `when` INTEGER, `with` TEXT, `resource` TEXT, `stanza` TEXT); ``` # Compatibility Does *NOT* work with 0.10 due to a conflict with the new archiving support in `mod_storage_sql`·
