ros_monitoring

This ROS package is intended to collect data from topics, transform, store, manage and send them to a MongoDB server. Being designed to maintain the collection even in connection drops with the server.

sudo chmod +x src/get*
cd ..
catkin_make

Installation of node_monitoring is recommended. Check the link:

Get the ROS running nodes (getNodes.py)

This package is intended to get the running nodes and connections between them. Publishing a message of type NodesInformation from ros_monitoring, in the publisher /nodesStatus

Published information (/nodesStatus)

The information published by this node is as follows:

{
    nodes:  [{
        node: -- node name.................as string
        publications: [{
            topic:    -- topic name....as string
            msg_type: -- message type..as string
        }, ...],
        subscriptions: [{
            topic:    -- topic name....as string
            msg_type: -- message type..as string
        }, ...],
        services: [ -- node name...........as string, ...]
    }, ...]
}

Get the connection with an IP and port (getSignal.py)

This topic should get the connection status between the computer running ROS, with other IPs pings periodically. The information is published in a message of type SignalInformation from ros_monitoring in the publisher /connectionStatus.

pinglist (pingList.py)

To configure which IPs the node will ping, you must edit the file pingList.py, which is a dictionary in the following format:

{   
    'ip':       -- IP to ping......as string
    'port':         -- Port to ping....as integer
    'interval': -- Ping interval...as integer
    'timeout':  -- Timeout ping....as integer
    'count':    -- Number of trys..as integer
}

Published information (/connectionStatus)

The information published by this node is as follows:

{
    Info_ping: [{
        is_alive:         -- The status of connection...as integer
        packets_sent:     -- Number of sent packets.....as integer
        packets_loss:     -- Number of loss packets.....as integer
        packets_received: -- Number of received packets.as integer
        port:             -- Port it was sent to........as integer
        rtt_max:      -- Maximum connection RTT.....as float
        rtt_min:      -- Minimum connection RTT.....as float
        rtt_avg:      -- Average connection RTT.....as float
        ip_target:    -- IP it was ping.............as string
        }, ...]
 }
