The Veeam Monitor Free Edition is an easy-to-use VMware monitoring solution designed to meet the day-to-day needs of VMware administrators who need real-time performance monitoring and alerting. Built from the ground up specifically for the virtual world, Veeam Monitor provides a bird’s-eye view of key performance metrics across your virtual ESXi infrastructure.

With Veeam Monitor, you can view real-time resource usage data for any virtual infrastructure object or collection of objects, as well as known infrastructure events, all on a single screen. This allows you to finally see your virtual infrastructure as a unified entity, not just a collection of isolated hosts and guests.

There are some limitations but fair enough to monitor and manage my ESXi hosts. I don’t have Virtual Center servers to manage my branch server ESXi systems and Veeam Monitor Free Edition will do all that for me know.

Some screenshots:

Latency in a packet-switched network is measured either one-way (the time from the source sending a packet to the destination receiving it), or round-trip (the one-way latency from source to destination plus the one-way latency from the destination back to the source). Round-trip latency is more often quoted, because it can be measured from a single point. Note that round trip latency excludes the amount of time that a destination system spends processing the packet. Many software platforms provide a service called ping that can be used to measure round-trip latency. Ping performs no packet processing; it merely sends a response back when it receives a packet (i.e. performs a no-op), thus it is a relatively accurate way of measuring latency.

I am using CactiEZ v0.3 to address this issue and monitor the ping latency. Those hosts may or may not be a SNMP enabled device. If the router is service provider managed than you probably won’t be able to get any access to SNMP, but for this we don’t need it.

a) Create new device in Cacti Management console. See example for www.networknet.nl

b) Choose for Availability “Ping” and use “ICMP” ping as method. Click Add and reopen the device.

c) Locate Associated Graph Templates and choose “Unix-Ping Latency” in the Graph Templates. Click Add.

d) Click “*Create Graphs for this Host”

e) Select “Create: Unix – Ping Latency” graph template and click Create.

f) Choose Red as legend color and click Create. + Created graph: www.networknet.nl – Ping Latency is now created.

i) Create new Graph Tree and add the new created graph for the network latency. See my example.

The result:
