HTTP Interface for Administration and Monitoring

GET /_admin/log

(reads the log information)

GET /_admin/log

Returns all fatal, error, warning or info log messages.The returned object contains the attributes:`lid`

: a list of log-entry identifiers. Each log message is uniquely identified by its`lid`

and the identifiers are in ascending order.

`level`

: a list of the log-level of the log-entry.

`timestamp`

: a list of the timestamp as seconds since 1970-01-01 of the log-entry.

`text`

: a list of the text of the log-entry.

`totalAmount`

: the total amount of log entries before pagination.

GET /_admin/log?upto=log-level

Returns all log entries upto log-level. Note that log-level must be:`fatal`

/`0`

`error`

/`1`

`warning`

/`2`

`info`

/`3`

`debug`

/`4`

GET /_admin/log?level=log-level

Returns all log entries of log-level. Note that `level=`

and `upto=`

are mutably exclusive. GET /_admin/log?size=size&offset= offset

Paginates the result. Skip the first offset entries and limit the number of returned log-entries to size. GET /_admin/log?start=lid

Returns all log entries such that their log-entry identifier is greater or equal to `lid`

. GET /_admin/log?sort=direction

Sort the log-entries either ascending if direction is `asc`

, or descending if it is `desc`

according to their `lid`

. Note that the `lid`

imposes a chronological order. GET /_admin/log?search=text

Only return the log-entries containing the text string.
GET /_admin/status

(reads the system status)

GET /_admin/status

The call returns an object with the following attributes:`system.userTime`

: Amount of time that this process has been scheduled in user mode, measured in clock ticks divided by sysconf(_SC_CLK_TCK) aka seconds.

`system.systemTime`

: mount of time that this process has been scheduled in kernel mode, measured in clock ticks divided by sysconf(_SC_CLK_TCK) aka seconds.

`system.numberOfThreads`

: Number of threads in this process.

`system.residentSize`

`system.virtualSize`

: Virtual memory size in bytes.

`system.minorPageFaults`

: The number of minor faults the process has made which have not required loading a memory page from disk.

`system.majorPageFaults`

POST /_admin/modules/flush

(flushs the module cache)

POST /_admin/modules/flush

The call flushes the modules cache on the server. See Modules Cache for details about this cache.
POST /_admin/routing/reload

POST /_admin/routing/reload

The reloads the routing information from the collection `routing`

.
GET /_admin/connection-statistics

(reads the connection statistics)

GET /_admin/connection-statistics?granularity=granularity&figures= figures&length= length

The call returns statistics about the current and past requests. The following parameter control which information is returned.- granularity: use
`minutes`

for a granularity of minutes,`hours`

for hours, and`days`

for days. The default is`minutes`

.

- figures: a list of figures, comma-separated. Possible figures are
`httpConnections`

. You can use`all`

to get all figures. The default is`httpConnections`

.

- length: If you want a time series, the maximal length of the series as integer. You can use
`all`

to get all available information. You can use`current`

to get the latest interval.

`resolution`

: the resolution in seconds aka granularity. The length of the time intervals.

`start`

: a list of time stamps in seconds since 1970-01-01. Each entry marks the start of an interval for which the figures were computed. The length of the interval is given by`resolution`

.

`length`

: the number of returned intervals.

`totalLength`

: the number of available intervals.

`httpConnections`

: the number of opened http connections during the interval.

`httpDuration`

: the distribution of the duration of the closed http connections during the interval.

`current`

the figures for the current interval are returned. Examples
