            "content": "The flushcached function connects to rrdcached, the RRD caching daemon, and issues a \"flush\"\ncommand for the given files. The daemon will put the files to the head of the update queue so\nthey are written \"soon\". The status will be returned only after the files' pending updates\nhave been written to disk.\n\nfilename\nThe name(s) of the RRD file(s) that are to be written to disk.\n\n--daemon|-d address\nAddress of the rrdcached daemon. If not specified, the RRDCACHEDADDRESS environment\nvariable must be set (see below).  For a list of accepted formats, see the -l option\nin the rrdcached manual.\n\nrrdtool flushcached --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd\n",

            "content": "The following environment variables may be used to change the behavior of\n\"rrdtool flushcached\":\n\nRRDCACHEDADDRESS\nIf this environment variable is set it will have the same effect as specifying the\n\"--daemon\" option on the command line. If both are present, the command line argument\ntakes precedence.\n",
