Node.js - spawn is cutting off the results - node.js

Question

I'm creating a node program to return the output of linux top command, is working fine the only issue is that the name of command is cutted, instead the full command name like /usr/local/libexec/netdata/plugins.d/apps.plugin 1 returns /usr/local+
My code
const topparser=require("topparser")
const spawn = require('child_process').spawn
let proc=null
let startTime=0
exports.start=function(pid_limit,callback){
startTime=new Date().getTime()
proc = spawn('top', ['-c','-b',"-d","3"])
console.log("started process, pid: "+proc.pid)
let top_data=""
proc.stdout.on('data', function (data) {
console.log('stdout: ' + data);
})
proc.on('close', function (code) {
console.log('child process exited with code ' + code);
});
}//start
exports.stop=function(){
console.log("stoped process...")
if(proc){proc.kill('SIGINT')}// SIGHUP -linux ,SIGINT -windows
}//stop
The results
14861 root 20 0 0 0 0 S 0.0 0.0 0:00.00 [kworker/1+
14864 root 20 0 0 0 0 S 0.0 0.0 0:00.02 [kworker/0+

22571 root 20 0 0 0 0 S 0.0 0.0 0:00.00 [kworker/0+
Any way to fix it?
Best regards

Answer 1

From a top manpage:
In Batch mode, when used without an argument top will format output using the COLUMNS= and LINES=
environment variables, if set. Otherwise, width will be fixed at the maximum 512 columns. With an
argument, output width can be decreased or increased (up to 512) but the number of rows is consid‐
ered unlimited.
Add '-w', '512' to the arguments.

Since you work with node, you can query netdata running on localhost for this.
Example:
http://london.my-netdata.io/api/v1/data?chart=apps.cpu&after=-1&options=ms
For localhost netdata:
http://localhost:19999/api/v1/data?chart=apps.cpu&after=-1&options=ms
You can also get systemd services:
http://london.my-netdata.io/api/v1/data?chart=services.cpu&after=-1&options=ms
If you are not planning to update the screen per second, you can instruct netdata to return the average of a longer duration:
http://london.my-netdata.io/api/v1/data?chart=apps.cpu&after=-5&points=1&group=average&options=ms
The above returns the average of the last 5 seconds.
Finally, you get the latest values all the metrics netdata monitors, with this:
http://london.my-netdata.io/api/v1/allmetrics?format=json
For completeness, netdata can export all the metrics in BASH format for shell scripts. Check this: https://github.com/firehol/netdata/wiki/receiving-netdata-metrics-from-shell-scripts
