Solaris Performance Tuning Basics




Before we dive into the details of Solaris performance tools pdf files, let's first review some basic concepts and principles of Solaris performance tuning. Solaris performance tuning is the process of optimizing the performance of your Solaris system by adjusting its settings and parameters according to your specific needs and goals.


Solaris performance tuning involves four main steps:


  • Collecting data: This is where you use various tools and commands to gather information about your system's performance metrics such as CPU utilization, memory usage, disk I/O, network traffic, etc.



  • Monitoring data: This is where you use various tools and commands to observe and track the changes in your system's performance metrics over time.



  • Analyzing data: This is where you use various tools and commands to interpret and understand the meaning and implications of your system's performance metrics.



  • Tuning data: This is where you use various tools and commands to modify and improve your system's settings and parameters based on your analysis results.



To perform these steps effectively, you need to follow two main strategies:


  • The by-layer strategy: This is where you analyze your system's performance by breaking it down into different layers such as hardware layer, kernel layer, application layer, etc. You then focus on each layer separately and identify the sources of performance problems and opportunities for improvement.



  • The 3-metric strategy: This is where you analyze your system's performance by focusing on three key metrics: throughput, latency, and utilization. Throughput is the amount of work done by your system per unit of time. Latency is the time it takes for your system to complete a unit of work. Utilization is the percentage of your system's resources that are being used.



To perform these strategies effectively, you need to understand the different components and resources that affect your system's performance such as:


  • CPU: The central processing unit is the brain of your system that executes instructions and processes data.



  • Memory: The memory is the storage space of your system that holds data temporarily while it is being processed by the CPU.



  • Disk: The disk is the storage device of your system that holds data permanently until it is deleted or overwritten.



  • Network: The network is the communication channel of your system that connects it to other systems and devices.



  • Process: A process is a program or application that runs on your system and performs a specific task.



  • Thread: A thread is a subunit of a process that executes a part of the program or application code.



  • Scheduler: The scheduler is the component of the kernel that decides which process or thread gets to run on the CPU and for how long.



  • File system: The file system is the component of the kernel that manages the organization and access of data on the disk.



  • Virtual memory: The virtual memory is the component of the kernel that manages the allocation and mapping of memory space for processes and threads.



Solaris Performance Tools Overview




Now that we have reviewed some basic concepts and principles of Solaris performance tuning, let's take a look at some of the tools that can help us perform it. Solaris performance tools can be classified into different types and categories based on their functionality and characteristics. Some of the common types and categories are:


  • System tools: These are tools that provide general information and statistics about your system's performance such as uptime, load average, CPU usage, memory usage, disk usage, network usage, etc. Some examples of system tools are vmstat, mpstat, iostat, sar, top, prstat, etc.



  • Process tools: These are tools that provide specific information and statistics about your system's processes and threads such as PID, PPID, UID, GID, priority, state, CPU time, memory size, disk I/O, network I/O, etc. Some examples of process tools are ps, ptree, pmap, pfiles, pstack, ptime, truss, etc.



  • Kernel tools: These are tools that provide detailed information and statistics about your system's kernel components and resources such as scheduler, file system, virtual memory, interprocess communication, etc. Some examples of kernel tools are kstat, cpustat, busstat, lockstat, cputrack, crash, mdb, etc.



  • DTrace tools: These are tools that use the DTrace framework to dynamically instrument and trace your system's kernel and user-level activities such as function calls, system calls, events, probes, etc. Some examples of DTrace tools are dtrace, dtruss, dapptrace, iosnoop, iotop, execsnoop, opensnoop, etc.



Each type and category of Solaris performance tools has its own advantages and disadvantages. Some of the common advantages and disadvantages are:


  • Advantages: They can provide useful and relevant information and statistics about your system's performance. They can help you identify and diagnose performance problems and bottlenecks. They can help you optimize and improve your system's performance.



  • Disadvantages: They can consume system resources and affect your system's performance. They can generate large amounts of output data that can be difficult to interpret and visualize. They can have different syntax and options that can be confusing and inconsistent.



To use Solaris performance tools effectively and efficiently, you need to know how to select the right tool for the right task. You also need to know how to use the tool properly and correctly. You need to know the common usage and syntax of the tool. You need to know what options and arguments to use with the tool. You need to know what output format and data to expect from the tool.


Solaris Performance Tools Examples




In this section, we will give you some examples of how to use Solaris performance tools to monitor and troubleshoot performance issues on your system. We will show you how to use some of the most popular and widely used tools such as vmstat, mpstat, prstat, iostat, sar, truss, dtrace and others. We will also show you how to interpret and visualize the output of these tools. We will also show you how to apply these tools to different scenarios and use cases.


vmstat




vmstat is a system tool that reports statistics about virtual memory (swap), CPU utilization (user/kernel/idle), process (runnable/blocked/waiting), page (in/out/fault), disk (read/write), interrupt (device/clock), context switch (voluntary/involuntary), etc. vmstat can be used to monitor the overall performance of your system and identify potential problems such as memory shortage, CPU saturation, disk contention, etc.


The common usage and syntax OK, I'm continuing to write the article. Here is the rest of the article with HTML formatting: of vmstat is: vmstat [interval] [count]


where interval is the time in seconds between each report, and count is the number of reports to display. If no arguments are given, vmstat displays a single report with the average values since boot. An example of vmstat output is: kthr memory page disk faults cpu r b w swap free re mf pi po fr de sr s0 s1 s2 s3 in sy cs us sy id 0 0 0 4596848 120908 0 3 0 0 0 0 0 0 0 0 0 1 1 1 0 0 100


The meaning of each column is: - kthr: kernel thread state (r: runnable, b: blocked, w: swapped) - memory: virtual memory usage (swap: available swap space, free: free memory) - page: page activity (re: page reclaims, mf: minor faults, pi: pages paged in, po: pages paged out, fr: pages freed, de: anticipated short-term memory shortfall, sr: pages scanned by clock algorithm) - disk: disk activity (s0-s3: number of transfers per second on each disk) - faults: trap and interrupt rate (in: device interrupts per second, sy: system calls per second, cs: context switches per second) - cpu: CPU utilization (us: user time, sy: system time, id: idle time) To interpret and visualize the output of vmstat, you can use the following guidelines: - If the r column is consistently high (more than the number of CPUs), it means that there are more processes ready to run than CPUs available. This indicates CPU saturation and high CPU demand. - If the b column is consistently high (more than zero), it means that there are processes blocked on I/O or other resources. This indicates I/O contention and high I/O demand. - If the w column is consistently high (more than zero), it means that there are processes swapped out to disk due to memory shortage. This indicates memory pressure and high memory demand. - If the swap column is consistently low (less than 10% of total swap space), it means that there is not enough swap space available for virtual memory. This indicates memory shortage and high memory demand. - If the free column is consistently low (less than 5% of total physical memory), it means that there is not enough free memory available for page cache and file system buffers. This indicates memory pressure and high memory demand. - If the re column is consistently high (more than zero), it means that there are pages reclaimed from the free list due to memory shortage. This indicates memory pressure and high memory demand. - If the mf column is consistently high (more than zero), it means that there are minor page faults caused by accessing pages that are not in memory but in the file system. This indicates file system activity and moderate I/O demand. - If the pi column is consistently high (more than zero), it means that there are pages paged in from disk due to memory shortage. This indicates memory pressure and high I/O demand. - If the po column is consistently high (more than zero), it means that there are pages paged out to disk due to memory shortage. This indicates memory pressure and high I/O demand. - If the fr column is consistently high (more than zero), it means that there are pages freed by the page daemon due to memory shortage. This indicates memory pressure and high I/O demand. - If the de column is consistently high (more than zero), it means that there is an anticipated short-term memory shortfall due to page-out activity. This indicates memory pressure and high I/O demand. - If the sr column is consistently high (more than zero), it means that there are pages scanned by the clock algorithm to find candidates for page-out. This indicates memory pressure and high I/O demand. - If any of the disk columns are consistently high (more than zero), it means that there is disk activity on that disk. This indicates disk utilization and I/O demand. - If the in column is consistently high (more than zero), it means that there are device interrupts per second. This indicates device activity and I/O demand. - If the sy column is consistently high (more than zero), it means that there are system calls per second. This indicates system activity and CPU demand. - If the cs column is consistently high (more than zero), it means that there are context switches per second. This indicates process activity and CPU demand. - If the us column is consistently high (more than 50%), it means that there is user time per second. This indicates user activity and CPU demand. - If the sy column is consistently high (more than 50%), it means that there is system time per second. This indicates system activity and CPU demand. - If the id column is consistently low (less than 50%), it means that there is idle time per second. This indicates CPU saturation and high CPU demand. To apply vmstat to different scenarios and use cases, you can use the following examples: - To monitor the overall performance of your system every 5 seconds, you can use: vmstat 5


- To monitor the memory usage of your system every 10 seconds for 20 times, you can use: vmstat -s 10 20


- To monitor the disk activity of your system every 15 seconds for 10 times, you can use: vmstat -d 15 10


mpstat




mpstat is a system tool that reports statistics about CPU utilization (user/kernel/idle) for each processor or processor set on a multiprocessor system. mpstat can be used to monitor the CPU load distribution and balance across different processors or processor sets.


The common usage and syntax of mpstat is: mpstat [interval] [count]


where interval is the time in seconds between each report, and count is the number of reports to display. If no arguments are given, mpstat displays a single report with the average values since boot. An example of mpstat output is: CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl 0 0 0 0 11 0 1 0 0 0 0 1 0 0 0 100 1 0 0 0 9 0 1 0 0 0 0 1 0 0 0 100


The meaning of each column is: - CPU: processor number or processor set ID - minf: minor faults per second - mjf: major faults per second - xcal: interprocessor cross-calls per second - intr: device interrupts per second - ithr: device interrupts as threads per second - csw: voluntary context switches per second - icsw: involuntary context switches per second - migr: thread migrations per second - smtx: spins on mutexes per second - srw: spins on read/write locks per second - syscl: system calls per second - usr: user time percentage - sys: system time percentage - wt: wait time percentage - idl: idle time percentage To interpret and visualize the output of mpstat, you can use the following guidelines: - If the usr column is consistently high (more than 50%) for a processor or processor set, it means that there is user time per second for that processor or processor set. This indicates user activity and CPU demand. - If the sys column is consistently high (more than 50%) for a processor or processor set, it means that there is system time per second for that processor or processor set. This indicates system activity and CPU demand. - If the wt column is consistently high (more than zero) for a processor or processor set, it means that there is wait time per second for that processor or processor set. This indicates I/O contention and I/O demand. - If the idl column is consistently low (less than 50%) for a processor or processor set, it means that there is idle time per second for that processor or processor set. This indicates CPU saturation and high CPU demand. - If the minf column is consistently high (more than zero) for a processor or processor set, it means that there are minor faults per second for that processor or processor set. This indicates file system activity and moderate I/O demand. - If the mjf column is consistently high (more than zero) for a processor or processor set, it means that there are major faults per second for that processor or processor set. This indicates memory pressure and high I/O demand. - If the xcal column is consistently high (more than zero) for a processor or processor set, it means that there are interprocessor cross-c OK, I'm continuing to write the article. Here is the rest of the article with HTML formatting: alls per second for that processor or processor set. This indicates interprocessor communication and synchronization overhead. - If the intr column is consistently high (more than zero) for a processor or processor set, it means that there are device interrupts per second for that processor or processor set. This indicates device activity and I/O demand. - If the ithr column is consistently high (more than zero) for a processor or processor set, it means that there are device interrupts as threads per second for that processor or processor set. This indicates device activity and I/O dem
