yCrash server capacity is dependent on number of crash analysis you intend to do. Here is
the rough estimate you can use.
Infrastructure: yCrash Server is platform agnostic. It can run on any infrastructure
(bare metal, cloud, container), any operating system(Unix, Linux, Solaris,
Windows,...).
Software: All it needs is Java 8 (or above) version. No other external softwares
needs to be installed.
CPU: Doesn't really matter. Any modest CPU capacity is fine.
Memory: You want to allocate 2x the size of your application's JVM heap size (i.e.
-Xmx). Let's say you want to monitor multiple applications whose heap size (i.e. -Xmx)
varies, then you want to pick the largest heap size. Let's say your largest application's
heap size is 2GB, then you want to allocate 4GB as the RAM size requirement for yCrash
server. If you would like to ensure high availability, yCrash server can be deployed on
multiple nodes behind a load balancer.
Storage: Again storage depends on the amount of crash reports you want to archive.
Approximately 100GB. yCrash's analysis results can be stored in local disk, NFS, AWS S3
storage, PureStorage (or any AWS S3 API compatible storages).
yCrash agent adds very negligible overhead (if at all it can be measured), for following
reasons:
a. Dormant: yCrash agent doesn't always run your server. It runs only when it's
triggered. Once triggered, it captures the dumps, transmits them to yCrash server and then
immediately becomes dormant.
b. Duration: yCrash agent runs for less than < 1 minute when triggered. Within this
time period it captures all the data and transmits to yCrash server. (Note: if your
application's heap size is large then it can take a few more seconds to complete).
c. Non-Intrusive: Unlike APM tools which run within the JVM, yCrash agent runs on the
server (outside the JVM). They don't intercept every single transaction. Only when a problem
happens, it reads and transmits dump files which are written to the disk. Thus It adds very
negligible overhead.
yCrash is platform agnostic. It can run on all the environments.
Yes, we do offer following discounts:
a. If you are planning to buy datacenter wide license, we offer site license at much
discounted price.
b. If you are going to buy more than 500 agent licenses, discount will be given.
c. If you are going to deploy the solution in developing countries, we give 'emerging
markets' discount.
No, currently Enterprise subscription is only offered for annual terms.
Cancellation: Your subscription will automatically terminate after the initial term.
Return: Once the license is delivered, the sale is final and cannot be returned. You will have the
option to discontinue your subscription after the initial term is over as we do not auto-renew.
Yes for selective few customers like apple we do host the tools exclusively for them. It is called as Hosted Enterprise Edition, where we will host tools exclusively for your organization (like http://youcompany.ycrash.io) in AWS cloud.
