Set­ting up Gan­glia and sflow in the cloud

OpenSource For You - - ADMIN -

In this guide, we are go­ing to set up a Gan­glia and sFlow mon­i­tor­ing sys­tem that will be able to dy­nam­i­cally mon­i­tor and re­port the per­for­mance of cloud in­stances in real-time.

EC2 com­puter servers, but can be repli­cated iden­ti­cally on any ma­jor cloud ser­vices provider in­clud­ing Eu­ca­lyp­tus, Opens­tack, Clouds­tack, etc.

Fig­ure 3 gives the set-up di­a­gram. In this sce­nario, we are us­ing two in­stances for demo pur­poses. One in­stance will con­tain the Gan­glia gmetad and gmond dae­mons, and the other in­stance will con­tain only the Host sFlow agent. The Host sFlow agent will con­tin­u­ously mon­i­tor the in­stance and send back the col­lected met­rics to Gan­glia’s gmond dae­mon, which in turn, will feed the met­rics to gmetad for pro­cess­ing and vi­su­al­i­sa­tion.

be mul­ti­ple such Host sFlow agents mon­i­tor­ing the CPU, net­work, disk work­loads and re­port­ing th­ese back to a sin­gle or even mul­ti­ple in­stances of Gan­glia. The de­sign can vary as per your re­quire­ment.
