InsightIQ 3.2.1: Cool new stuff

[Editor’s note: We updated the title from InsightIQ 3.2 to InsightIQ 3.2.1, changed mentions of 3.2 to 3.2.1, and removed the original photo on 8/5/2015. InsightIQ 3.2 is replaced by InsightIQ 3.2.1. All the cool new features mentioned in this blog are available in InsightIQ 3.2.1, including a fix for an upgrade issue. For more information, refer to InsightIQ 3.2.1 release notes. And while we originally featured the “Deal with It” meme photo because it showcased the ultimate symbol of cool (wearing sunglasses indoors), we no longer considered it a good fit for this blog post. Call it a case of revenge of the meme. For questions or concerns about this blog post, please send an email to isi.knowledge@emc.com.]

Being cool isn’t just about expensive clothes and wearing sunglasses indoors. Being cool is about attitude, speed, and efficiency. Slow is never cool. InsightIQ 3.2.1 is easily the coolest release of InsightIQ yet. If you want to know why, keep reading.

New, faster, lighter PostgreSQL database

InsightIQ 3.2.1 has a sweet new PostgreSQL database instead of the old SQLite database. PostgreSQL offers the monitoring experience you’ve been waiting for. With the new PostgreSQL datastore, InsightIQ runs faster and requires less space to store the same amount of information. It’s the best of both worlds, and nothing is better than the best of both worlds, except maybe the best of three or four worlds. But really, how many worlds do you need?

Configurable stat collection

While earlier versions of InsightIQ were obsessed with collecting every single cluster statistic, InsightIQ 3.2.1 is a little more laid back. InsightIQ 3.2.1 enables you to specify which statistics you want to collect, so you have more room on your hard drive for videogames. If you just don’t care about CPU usage, InsightIQ is right there with you.

Datastore export

In previous versions of InsightIQ, if you wanted to transfer cluster data from one InsightIQ instance to another, you had to connect the two instances and keep them connected while the data was migrated. Those were the rules; that’s just the way things were. But InsightIQ 3.2.1 doesn’t play by the rules. It’s a lone wolf that stays up past midnight and drinks milk from the carton. InsightIQ 3.2.1 lets you export your datastore to a .tar file that you can later import to any number of other InsightIQ instances, and it lets you do it on your own time.

SmartPools support

InsightIQ 3.2.1 also enables you to break out performance data by node pools and tiers, which is more useful than cool, but does everything have to be cool? The answer is yes… and no. Because there are no definitive answers in life, only questions. And thinking like that makes you really cool.

At this point, you probably can’t wait to start working with InsightIQ’s new database, move some datastores around, and apply a few node-pool breakouts. And the great thing is: you don’t have to! Follow the link below to start right now. The 1,000,000th user to click wins a free skateboard!*

EMC Isilon InsightIQ 3.1.1 enhancements

No tool is so perfect that it cannot be improved. There’s no knife that couldn’t be sharper, no couch that couldn’t be comfier, no paperweight that couldn’t be heavier. EMC Isilon InsightIQ is a powerful tool, but it can always be made more powerful. That’s why we recently released InsightIQ  3.1.1: to make InsightIQ run faster and more reliably than ever before.

Enhancements

SPOILER ALERT: The following text describes some of the awesome new enhancements of InsightIQ 3.1.1. DO NOT READ if you just want to be pleasantly surprised when you download it.

Speed

Have you ever hiked up a mountain only to discover that your backpack was full of rocks? If so, you’re a really bad camper (or possibly just a geologist), but either way, you could have made that hike a lot faster without the rocks.

You may notice while running the new version of InsightIQ that it’s a lot faster than before. We’ve removed the rocks by tweaking InsightIQ to run more efficiently, including making improvements to debugging behavior. We’ve removed a lot of unnecessary debugging effort, which frees InsightIQ resources to work on more important things.

We’ve also improved InisghtIQ’s datastore technology. In previous versions, InsightIQ would let disk-space usage data take up more than its fair share of space in the InsightIQ datastore. InsightIQ 3.1.1 makes sure that free space is divided up equally for all.

Stability

InsightIQ 3.1.1 includes improvements to monitoring stability, especially for large clusters. Earlier instances of InsightIQ would request a lot of data from large clusters all at once, which could cause the clusters to become confused and passive aggressive. InsightIQ 3.1.1 has learned to be more patient and build a healthier relationship between it and the monitored clusters.

We’ve also improved stability by correcting an error in InsightIQ’s timeout behavior. Have you ever noticed InsightIQ’s connection timing out more than usual? This was likely due to InsightIQ interpreting a timeout value of 0 as actually meaning 0 (instead of infinity). We’ve reconfigured InsightIQ to fix this issue and stop taking things so literally.

Finally, we’ve made some adjustments to reduce “data retrieval delayed” errors. When previous versions of InsightIQ would lose a connection to the cluster, InsightIQ would sometimes report a data retrieval delayed error indefinitely, rather than report that the connection had been severed. This led to some difficulty diagnosing the issue.
