What do you mean? you give limited info. If you you mean you only see 1000 in debug sidecar, that is because the sidebar truncates for performance reasons the array is still there in memory. e.g array size 25000 ```auto [{"id":"3decb5f518882686","type":"subflow","name":"live debug","info":"localhost/debug","category":"","in":[{"x":240,"y":160,"wires":[{"id":"45dbf990.ba2408"}]}],"out":[{"x":560,"y":160,"wires":[{"id":"45dbf990.ba2408","port":1}]}],"env":[{"name":"debug_name","type":"str","value":"Debug","ui":{"label":{"en-US":"Name"},"type":"input","opts":{"types":["str"]}}},{"name":"debug_property","type":"str","value":"msg","ui":{"label":{"en-US":"Property Path"},"type":"input","opts":{"types":["str"]}}},{"name":"pass_debug_property","type":"bool","value":"false","ui":{"label":{"en-US":"Pass Property Path"},"type":"input","opts":{"types":["bool"]}}}],"meta":{"module":"Live_debug","type":"common","version":"0.0.1"},"color":"#DDAA99"},{"id":"45dbf990.ba2408","type":"function","z":"3decb5f518882686","name":"format time nicely","func":"let msg1 = {payload: RED.util.cloneMessage(msg)};\nmsg1.payload.debug_property = msg.debug_property || env.get(\"debug_property\") || \"msg\"\ntry {\n msg1.payload.debug_property_array = RED.util.normalisePropertyExpression(msg1.payload.debug_property)\n}\ncatch(error){\n msg.payload = error;\n msg1.payload.error = error;\n}\nmsg1.payload.debug_name = env.get(\"debug_name\") || msg._msgid || \"name error\"\nmsg1.payload.pass_debug_property = env.get(\"pass_debug_property\") || false\nreturn [msg1,msg];","outputs":2,"noerr":0,"initialize":"","finalize":"","libs":[],"x":390,"y":120,"wires":[["50da04b3.af25fc"],[]]},{"id":"50da04b3.af25fc","type":"websocket out","z":"3decb5f518882686","name":"","server":"985ecbc7.67a138","client":"","x":680,"y":120,"wires":[]},{"id":"1787be40.e87842","type":"http in","z":"3decb5f518882686","name":"","url":"/debug","method":"get","upload":false,"swaggerDoc":"","x":330,"y":40,"wires":[["1857548e.e7a8ab"]]},{"id":"1857548e.e7a8ab","type":"template","z":"3decb5f518882686","name":"Simple Web Page","field":"payload","fieldType":"msg","format":"html","syntax":"mustache","template":"\n\n \n \n Debug Messages\n \n \n \n \n

I have to store 10000-50000 items in array but seems like there is limit of adding element in that number? so is there any setting to increase this number ---

What makes you think there is a limit? ---

What do you mean by limit? Javascript arrays can contain up to 2^32 elements, so that should be more than enough. 😉 Here is some relevant info on the basics of arrays in Javascript: > **[Array - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)** > > The Array object, as with arrays in other programming languages, enables storing a collection of multiple items under a single variable name, and has members for performing common array operations. Furthermore, JS is rather lenient regarding array size, you can push new elements or set indexes without explicitly increasing the size. Here's more info on the [length](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/length) property. ---
