If a new message doesn't come in (the count down gets to 0) a message is generated. count == 1, the next msg. count if known, the total number of messages in the sequence. Whilst your flow may not use nodes that depend on Discussion. A simple queue node that store incoming messages in memory queue and uses a feedback from a following action or trigger message to release the next message stored in the queue. index should be in {0 . A Node Red node for measuring flow message speed, i. payload (instead of msg), then use the batch node to combine them and the join node to merge them into an array of objects. and starts a 5 second count down. I'm very new to function nodes (as a matter of fact I've been avoiding node-red-contrib-spike-counter. Stop node red and start it again in a terminal and leave the terminal open while you watch it and see if node-red restarts I very nearly posted a repeat of this request, but instead I'll ask if anything further has happened with it. However it would have been better if I had a "node-red-contrib-msg-statistics" node, which calculated both the speed and the size. First message (msg. Hello, I am catching the string "null" from a msg and i am incrementing a counter every time it shows up (normally there is a number), at least i'm trying to. payload=i; node.

Does anyone have The msg-counter node is an easy way to monitor and count the flow of messages in your Node-RED applications. ; Default Step: Default amount that will be incremented or decremented on every incoming message. There are two main nodes for modifying a message, the Any chance to have a real log on SSH of all the messages of the flow? Or a counter somewhere on the web ui? Currently, you need to insert a debug node in the right place and set it to dump to console only which avoids updating the debug panel. For example when the frequency is '1 minute', it will count all the messages received in the last minute:. You could also add a counter node and display the count only on the debug node: The other thing which is sticking out to me is that in your screen shots BOTH messages have the same topic. It is often useful to be able to pass message properties through a node unaffected, and those will get lost if you make a new message. To install this node, you can clone it into your Node-RED node directory or install it directly from npm: npm install node-red-contrib-cyclic-counter Then restart Node-RED, and the cyclic counter will be available in the function category. I got the following flow but it just sen Hi there, I'm having trouble to put my flow to work. group must be identical for all parts; msg. Well, you should already know that. msg. however, some messages are empty, and hence dont take any amount of time, so i need to wait for 20 seconds unnecessarily, hence i added a msg. send(msg); i--; } Expected output 10 9 8 7 6 5 Good day, I expect that i made a realy simple mistake. Maximum Count Since your original flow uses GET nodes, I parameterized the URLs (e. The msg-counter node is an easy way to monitor and count the flow of messages in your Node-RED applications. I then read these values into node-red via the MQTT subscribe node. Because the name "node-red-contrib-msg-speed" was not really suitable to add size measurements, I decided at the end to create a separate node "node-red-contrib-msg-size". I need your help to finish this part. Each time a message passes through this node, it increments a counter and sends the message as a JSON payload which includes the message's payload, topic, and I have a flow in which there are nearly 20 messages coming from a node and i split them to process individually so i set a rate limit of approx 20 seconds. A Node-RED flow works by passing messages between nodes. e. The idea is that when a message arrive the output count down. A node that counts messages received in a specified time limit.
