#### MacOS not recognizing variables in url
- Solution:
quoting the url would solve the problem

root@MacBookPro zabbix_api_v6 % curl 172.16.1.70:8880/show?pretty
zsh: no matches found: 172.16.1.70:8880/show?pretty

root@MacBookPro zabbix_api_v6 % curl "172.16.1.70:8880/show?pretty"
{
    "zabbix_probe": {
        "0": {
            "31687": {
                "name": "CPU idle time",
                "probe_server": "172.16.1.70"
            },
            "31694": {
    ...

#### Daemon not exiting correctly (didn't write to config)
- Solution:

This is due to "atexit" not responding to signals from other handler.

A function was assigned to signal. Instead of exiting directly, SIGTERM would call sys.exit in order to trigger atexit function.

def sigHandler(signo, frame):
    sys.exit(0)
    
signal.signal(signal.SIGTERM, sigHandler)
