graph definition: file pattern
Hi,
I'm looking for a way to influence the rrds in a multi-rrd graph. I use FNPATTERN, but I want to have more control from the url because the graphs I want can change from server to server.
As example, this is a graph with 4 filesystems: hobbitgraph.sh?host=serverA& service=disk& first=1& count=4& action=menu
But I want to specify the filesystems I want to see: hobbitgraph.sh?host=serverA& service=disk& rrd=/,/home,/usr& action=menu
An other solution for my case is the possibility to overrule the FNPATTERN in the config file from the url. For instance, I want to change the FNPATTERN from [disk] so it only shows the filesystems beginning with /home: hobbitgraph.sh?host=serverA& service=disk& FNPATTERN=disk,home(.*).rrd& action=menu
The url's to the graphs are generated externally from xymon. I use the filesystems as example. I need this to group hdisk information on AIX per VG.
Any thoughts?

For those who are interested, I hacked myself a patch. This allows you to add a CGI parameter cgipat with a regular expression. For instance, if you want to match all filesystems beginning with /home, add this to the url: cgipat=/home.*
57d56 < char *cgipat = NULL; 218,220d216 < else if (strcmp(cwalk->name, "cgipat") == 0) { < cgipat = strdup(cwalk->value); < } 719,722d714 < if (cgipat) { < addtobuffer(result, "&cgipat="); < addtobuffer(result, urlencode(cgipat)); < } 927c919 < pcre *pat, *expat = NULL, *cgipatt = NULL ;
pcre *pat, *expat = NULL;
958,969d949 < if (cgipat) { < cgipatt = pcre_compile(cgipat, PCRE_CASELESS, &errmsg, &errofs, NULL); < if (!cgipatt) { < char msg[8192]; < < snprintf(msg, sizeof(msg), < "CGIpat error, PCRE pattern %s invalid: %s, offset %d\n", < htmlquoted(cgipat), errmsg, errofs); < errormsg(msg); < } < } < 989,994d968 < < if (cgipatt) { < result = pcre_exec(cgipatt, NULL, d->d_name, strlen(d->d_name), 0, 0, < ovector, (sizeof(ovector)/sizeof(int))); < if (result < 0) continue; < }
