Graphite - confusion in groupByNode + sum.* + sumSeries -


i not sure if right place question, because have seems working not sure how.

i have multiple servers logging graphite server. have following log lines logging failurereasons these servers graphite server. second parameter in addstatstoinvigilator() call prefix w.r.t. graphite - 

$status = $this->_db_new->put ( $init_key_new, $bins, $expirytime, $option_new ); if ($status != aerospike::ok)  {     addstatstoinvigilator ( "admarvel", "delivery.aerospike.migration.fc.get.failures", 1 );     addstatstoinvigilator ( "admarvel", "delivery.aerospike.migration.fc.get.failurereasons.$status", 1 ); logtofile("[{$this->_cluster_id}] failed key $key new aerospike cluster ", 'aero_debug_' . date ( 'h' ) ); }

where $status result of aerospike::put() function call , integer status code.

on plotting following graph, can see getting expected value -

target=groupbynode(admarvel.fam.*.delivery.aerospike.migration.fc.get.successes.sum.*,10,'sumseries')

enter image description here

there multiple worms in graph corresponding multiple servers logging graphite server.

i cross checked readings against 1 server counting total number of lines logged logtofile() in single minute on server.

so, graph seems show me number of timeouts per minute each server, not sure 2 summations doing - sum.* , sumseries. here documentation of sumseries

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
