Good Evening!!

I was running in node-red on windows PC, no interrupt on my node flow.  
But, here I have problem in My Local Disk: **"C"** drive memory has raising day by day.

On Windows, you have to know how you started Node-RED as that defines where the log goes (if anywhere).

Windows does not redirect console output to a log file by default

To capture output you need to redirect it:

```auto
node-red > node-red-log.log

```

This will create a new file each time you start node-red

So if you want to append:

```auto
node-red >> node-red-log.log

```

If you want separate logs:

```auto
node-red 2>node-red-error.log 1>node-red-log.log

```

Or if you like to mix outputs (stdout & stderr) in one single file you can use:

```auto
node-red > node-red.log 2>&1

```

Node v12 is REALLY old and no longer in support. You should be on Node 18LTS at least

If you use PM2 for running node-red on Ubuntu (rather than the usual method using systemd) then you will have to do something to manage the logs. Using systemd logs are automatically rotated.

No, not really. You absolutely need to find out how you are running Node-RED. You've not even shared where those log files exist.

There are multiple ways to start long-running services on Windows. Look in Task manager, there is a "start-up apps" section, right-click on the column headings are add the startup type and command line columns then look for Node-RED.

As your above message, I had look into task manager options there is no node-red app icon present. I have attached the corresponding image as given.

Is it that you have forgotten how you installed and run node red, or have you taken over the system from someone else?

That is a very short list. Much shorter than a standard PC I think. So I don't think you are seeing everything. Is that a corporately managed PC? If so, I would imagine that Node-RED is being run under a different service ID?

Alternatively, I see that you are using Siemens TIA - I think that might have Node-RED built-in but I think that is a remote instance not local?

Of course, that is remote instance. In, task scheduler there is node-red task is running.

In that case, you do know how Node-RED is running? What are the parameters/settings?
