Overview
This page describes the message and service types used by arni. This information might be out of date, for recent data look here: https://github.com/ROS-PSE/arni/tree/master/arni_msgs
Message Types
HostStatistics
Contains statistics about a host's resource usage.
# ip of the host string host # the statistics apply to this time window time window_start time window_stop # cpu float32 cpu_temp_mean float32 cpu_temp_stddev float32 cpu_temp_max float32 cpu_usage_mean float32 cpu_usage_stddev float32 cpu_usage_max float32[] cpu_usage_core_mean float32[] cpu_usage_core_stddev float32[] cpu_usage_core_max float32[] cpu_temp_core float32[] cpu_temp_core_mean float32[] cpu_temp_core_stddev float32[] cpu_temp_core_max # gpu float32[] gpu_temp_mean float32[] gpu_temp_stddev float32[] gpu_temp_max float32[] gpu_usage_mean float32[] gpu_usage_stddev float32[] gpu_usage_max # ram float32 ram_usage_mean float32 ram_usage_stddev float32 ram_usage_max # network string[] interface_name int32[] message_frequency_mean int32[] message_frequency_stddev int32[] message_frequency_max # bandwith of each network interface float32[] bandwidth_mean float32[] bandwidth_stddev float32[] bandwidth_max
NodeStatistics
Contains statistics about a node's resource usage.
#ip of the host this node belongs to string host #identifier of this node string node # the statistics apply to this time window time window_start time window_stop #CPU float32 node_cpu_usage_mean float32 node_cpu_usage_stddev float32 node_cpu_usage_max float32[] node_cpu_usage_core_mean float32[] node_cpu_usage_core_stddev float32[] node_cpu_usage_core_max #GPU float32[] node_gpu_usage_mean float32[] node_gpu_usage_stddev float32[] node_gpu_usage_max # ram float32 node_ramusage_mean float32 node_ramusage_stddev float32 node_ramusage_max # network load of the node float32 node_message_frequency_mean float32 node_message_frequency_stddev float32 node_message_frequency_max float32 node_bandwidth_mean float32 node_bandwidth_stddev float32 node_bandwidth_max # Drive I/O statistics of the node float32 node_write_mean float32 node_write_stddev float32 node_write_max float32 node_read_mean float32 node_read_stddev float32 node_read_max
RatedStatisticsEntity
Contains comparisons of expected value and actual value for a statistic.
# type of statistic like cpu_usage_core or cpu_usage
string statistic_type
# the value of the type
string[] actual_value
# the expected value like "40 - 70"
string[] expected_value
# constant
uint8 HIGH=0
uint8 LOW=1
uint8 UNKNOWN=2
uint8 OK=3
# state of the metadata from the node/host/connection :
# state: { 0 = high ; 1 = low ; 2 = unknown; 3 = ok}
uint8[] state
RatedStatistics
Contains an array of RatedStatisticsEntities for a node, host , or connection.
# name of node/host/connection string seuid # only used if seuid is a node. is the host ip the node runs on. string host # the rated statistics apply to statistics from this time window time window_start time window_stop # an array of rated entities RatedStatisticsEntity[] rated_statistics_entity
MasterAPIEntity
Represents a single entry of the master API
string name string[] content
MasterApi
Contains all the information masterApi.Master.getSystemState returns which is information about publishers, subscribers and services.
# publisher MasterApiEntity[] pubs # subscriber MasterApiEntity[] subs # services MasterApiEntity[] srvs
Service Types
NodeReaction
Stop or restart a node on a host or execute a shell command on host
# identifier of the affected node string node # action [restart, stop, command] string action # command (for action command) string command --- # message returned upon completion string returnmessage
StatisticHistory
Receive a History of the last few statistics send out
# get all statistics where timestamp in ms is > than timestamp time timestamp --- # each statistic has its own rated statistic. # timestamps can be found at the time windows of each statistic HostStatistics[] host_statistics RatedStatistics[] rated_host_statistics NodeStatistics[] node_statistics RatedStatistics[] rated_node_statistics rosgraph_msgs/TopicStatistics[] topic_statistics RatedStatistics[] rated_topic_statistics
