vCloud Director 1.5 cannot upload files error
Sep 5th
Let’s say you have your vCloud Director cells behind a load balancer.
You try to upload your files (.iso and .ovf images for either a vApp or media and receive an error message like:
Error: Transferring files
On page 98 of the vdc_15_admin_guide.pdf you will find a paragraph pointing out that you need to fill in the API field for uploads to work.
During the initial configuration of each cloud cell, you specified an HTTP service IP address. By default, vCloud Director uses that address in the XML responses from the REST API and as the upload target for the transfer service (for uploading vApp templates and media). To use a different address, specify a public REST API base URL.
I had missed that in my new setup of vCloud Director 1.5 and a helpful VMware employee answered my questions in the Communities.
Install of vCloud Director 1.5 fails to set up ESXi 4.1U1 hosts
Sep 5th
According to the install documentation, VMware vSphere 4 ESX and ESXi 4.1 update 1 are supported.
Install or upgrade to vCloud Director 1.5 will fail with the following error when trying to add the provider vDC:
Could not retrieve state for sequence: seq_os
This is easily fixed by editing the database table [os_id] and inserting the relevant information.
vCloud Director Cluster got you down?

vCloud Director – the VMware solution to building on-demand infrastructure for the enterprise and cloud computing…works.
But there are some trials you must encounter and complete before things work smoothly.
TL;DR: I failed at first but found the problem with the issue being firewall services blocking inter-cell communications. This post is about the log entry and how it isn’t very clear that there is an error to resolve.
MySQL, data partitioning, and me

So I have this database of bytes transferred from many of the devices on our network.
It queries these devices every 5 minutes storing many pieces of data, from the number of packets in and out to the number of bytes (or octets in network speak) in and out on an interface. (it also gathers statistics on errors, Cisco environment items, discards, etc). I am mostly concerned with the bytes transferred, so while the other data is collected – I am not using it at this point.
But what happens when you have 16 months worth of data?
Before you say ‘i dunno’, I’ll tell you: it is slow to query it back out, even with minimal indexes.
I have ~54 GB of data (including indexes), and 250 tables (each device has multiple tables, each table stores one type of data only).
So, how to get some speed back? Read on!
