_renew_logcache($c)update the logcache (internal sub)
close_logcache_connections($c)close all logcache connections
lmd_stats($c)return lmd statistics
_get_macrosreturns a hash of macros
replace_macros($string, $args, [$macros])replace macros in given string.
returns ($result, $rc)
$args should be: { host => host object (or service object) service => service object skip_user => 0/1 # skips user macros args => list of arguments }
get_macros($args)returns a hash of macros
$args should be: { host => host object (or service object) service => service object skip_user => 0/1 # skips user macros filter_user => 0/1 # filters user macros args => list of arguments }
_get_replaced_stringreturns replaced string
_get_obfuscated_stringreplace sensitive data with ***
_set_host_macrosset host macros
_set_service_macrossets service macros
_do_on_peers($function, $args, [ $force_serial ], [ $backends ], [ $raw_result ])returns a result for a function called for all peers
$function is the name of the function called on our peers
$args is a hash:
{
backend => [] # array of backends where this sub should be called
}select_backends($function, [$args])select backends we want to run functions on
_get_result($peers, $function, $args)run function on several peers and collect result.
_get_result_lmd($peers, $function, $arguments)returns result for given function using lmd
_get_result_serial($peers, $function, $arguments)returns result for given function
_get_result_parallel($peers, $function, $arguments)returns result for given function and args using the worker pool
remove_duplicates($data)removes duplicate entries from a array of hashes
reset_failed_backends([ $c ])Reset failed backends cache. Retries are useless unless reseting this cache because failed backends won't be asked twice per request.
AUTOLOAD()redirects sub calls to our backends
DESTROY()destroy this
sort_result($data, $sortby)sort a array of hashes by hash keys
sortby can be a scalar
$sortby = 'name'
sortby can be an array
$sortby = [ 'name', 'description' ]
sortby can be an hash
$sortby = { 'DESC' => [ 'name', 'description' ] }_sort_nr($data, $sortby)sort a array of array by array nr
sortby must be an array
[<nr>, <direction>]
ex.:
[5, 'asc']
[5, 'asc', 13, 'desc']_limit($data, $limit)returns data limited by limit
_set_user_macros($args, $macros)Sets the USER1-256 macros from a resource file. Shinken supports all kind of macros in resource file, so just replace everything from the resource file.
$args should be: { peer_key => peer key for the host filter => 0/1 # only add allowed macros file => location of resource file args => list of arguments }
