undefined function apache_getenv()

[bzub]

My webserver stack is CentOS 6.4 + Apache + php-fpm via mod_fastcgi.so. I've tried Ubuntu 12.04 also.

Everything seems to work up until I run a query for a graph, at which point the browser shows:

POST http://tsdbserver:8080/adhoc/search/OpenTSDB [HTTP/1.1 500 Internal Server Error 42ms]

In the php-fpm logs I see:

PHP Fatal error:  Call to undefined function apache_getenv() in /vm/prod/StatusWolf/lib/StatusWolf/Model/Datasource/OpenTSDB.php on line 277

Does StatusWolf depend on an Apache + mod_php setup? Thank you.

I finally found that apache_getenv() isn't available when using PHP through a CGI system. I can submit a patch soon that should make StatusWolf work in more environments unless I'm missing something.

Basically change line 277 in Model/Datasource/OpenTSDB.php to:

      $cache_key = md5($query_bits['key'] . $this->downsample_interval . $this->downsample_type . $_SERVER["SERVER_ADDR"]);
