Hi All,
I use smokeping here for network measurement, however in a slightly "different" configuration. As I need to run the network-tests in distributed mode, but security-rules descide that there can be no connection from outside (where my "slaves" are located) to "inside" (where the central server is), I need to use a different approuch. - On the "slaves", I run a number of probes, just as seperate perl programs, driven by crontab and storing their information into a local mysql database. - Our "master" periodely extracts this information from the slaves and does a "rrdtool update" of a number of rrd-files locally on the master-server. - Smokeping.cgi is then used, but only as a visualisation-tool. In general, this works pretty good, with one exception: I cannot get the "multihost" to work. When I addapt the "/etc/smokeping/config" file in the way it is descibed in the documentation, the smokeping.cgi script does not seams to concider this to be a "multhost" graph. It just gives an error as follows: "ERROR: opening '/var/lib/smokeping/Slave1/multihost.rrd': No such file or directory" So the GUI seams to think this is a "normal" graph and -hence- looks for a matching rrd-file. The strange this is that -when you actually make a real working multihost setup on a test-server (as described in the documentation on the websites), smokeping does NOT create any "multihost.rrd" file anywhere on the test-server. So, it seams to be that the GUI somehow knows this graph is a multihost graph and must be processed differently. So, the question is this: How does smokeping.cgi differenciate between a "multihost" graph and a normal one? BTW. If somebody has idea about our setup, please feel free to comment. The objectives I need are: - distributed polling - "master" must be located inside our network. Slaves are on the plain internet. - Communication can only be set up from the inside to outside - The system needs to be able to keep on working if the communication between the master and the slaves is interrupted. Cheerio! Kr. Bonne. -- jabber/gtalk: [email protected]
