website - MODx - Php code isn't updating -

i have been using snippets power "server status" page minecraftservers, , working fine quite while, reason php code not updating! (it became clear when our servers went down, , sadly server status snippets not updating, , quite few of our users getting confused!)

if receive help, awesome-

problem:

php snippets not updating (not after 24 hours)

desired result:

is there way make update every 2-3 minutes when being used, if no 1 goes page, not update @ all..?

snippet code: on pastebin

modx version - revolution 2.2.6-pl

this due caching.

caching in modx means system creates individual file each resource in site. these files built snippets, chunks , placeholders may have in template , elements being parsed.

if chose cache these snippets or chunks, modx not call code again, output content generated first time cache created.

these cached:

[[mysnippet]] [[$mychunk]] 

these uncached:

[[!mysnippet]] [[!$mychunk]] 

please note want use caching possible, snippet describing (different output without removing cache) require uncached tags.
