Simple expand macros on stdin

[limo]

Hi to all,

I just needed this so I made little patch. It is working for me, but it is more hack than real patch. I added commandline options to zabbix_server

       "  -n --new-nodeid <nodeid>    convert database data to new nodeid",
       "  -e --expand-macros          expand macros on stdin and print to stdout",
       "  -t --expand-macros-triggerid  <triggerid> for -e and simple_macros: triggerid",

than you can use zabbix_server with parameter -e and -t :

 ./zabbix_server  -e -t '19524' -c /etc/zabbix/zabbix_server_beta.conf
{a423-1:icmpping.last(0)}
{HOSTNAME}
ctrl-d

1
A423-1

It is not safe and sure alex will don't like me for my hacks but mysticaly, it works we use it as external alerter script which substitutes macros in external files.

The idea is very good but I don't like this patch at all! It is clearly not a task of zabbix_server!

Yes, you are absoulutely right! I do not like this patch too! But as I said it works for me and it was easiest way to achieve

If you think idea is good so maybe it could look something like:

zabbix_cli [ --expand-stdin [ {--triggerid id} |  {--hostid id} | {--eventid id} ]  ]

which would expand stdin to stdout

zabbix_cli [ --expand macro_name [ {--triggerid id} |  {--hostid id} | {--eventid id} ]  ]

which would expand only one macro_name and return value to stdout.

But maybe it would be easier and quicker to expand across tcp/ip port. So some server process could listen on some port (or use some protocol on same port) which would do only this translation with simple API.

With regards,

I think that a command line utility would be the best solution for this and similar tasks.

Well I am going to try this and by the looks of it, it is very nice work and I like it already, just thought you should know!
