HP-UX Version & Recent Enhancement Information

The current version of SarCheck for HP-UX is: 7.01.30

    Enhancements to version 7.01.30 (November 8, 2016):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • If any of SarCheck's internal tables become more than 80 percent full, an informational message will be printed showing how full all of the tables are. This is designed to help us understand the requirements of various systems that use SarCheck and does not indicate a system problem.
    • A message asks our customers to let us know if they're still running the HP-UX 10.x operating system, and the message should only appear on 10.x. We want to streamline our code and eliminate what we believe is obsolete code.

    Enhancements to version 7.01.29 (May 17, 2016):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Support the gnuplot terminal type "pngcairo"

    Enhancements to version 7.01.28 (April 14, 2016):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Rewrite some of the disk analysis code to improve efficiency
    • Fix an inconsistency in the logic used to produce and display seven possible graphs

    Enhancements to version 7.01.27 (October 7, 2015):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Begin adding info on where recommendation data came from, for example: sar -u
    • Remove a stray "1" in a gnuplot 4.2+ script for multi-day data, causing the production of the CPU graph to fail
    • Add comment to gnuplot scripts saying what gnuplot version was expected

    Enhancements to version 7.01.26 (January 8, 2015):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Only report the cpu/wio correlation coefficient if there are more than 5 samples
    • Add the cpu/wio correlation coefficient to the tabular summary

    Enhancements to version 7.01.25 (October 8, 2014):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • The correlation between CPU Utilization (%usr + %sys) and Waiting for I/O (%wio) in the sar -u report is calculated and any significant correlation is reported. A strong negative correlation typically infers an I/O bottleneck and a strong positive correlation is a sign of a healthy system.

    Enhancements to version 7.01.24 (June 16, 2014):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • The legend for the swap in/out, total I/O, and number of processes graphs has been changed to show the peak value. This should improve readability when the graphs are seen without the surrounding text in the report.

    Enhancements to version 7.01.19 (May 28, 2013):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • If no -html, add an asterisk to the -t table data when values are outside the thresholds
    • Make the default usage text screen fit in an 80x25 window
    • If there's no data to analyze don't display the -t summary table
    • Fix a few misspelled words in text file

    (Subscription holders: If you'd like this version, ask your sales rep)

    • Fixed a typo in the ondemand script
    • Add the -lp switch, to allow the analysis of both legacy and persistent disk names in 11.3 data. This will result in SarCheck pre-7.01.07 behavior.
    • Add the LP keyword to the sarcheck_parms file, to allow the analysis of both legacy and persistent disk names in 11.3 data. This will result in SarCheck pre-7.01.07 behavior.
    • Supress the analysis of the maxvgs tunable parameter, obsolete in 11.3. When analyzing 11.3 data, especially on a pre-11.3 system, recommendations to this parameter were occasionally generated.

    (Subscription holders: If you'd like this version, ask your sales rep)

    • Support longer sar report file names. The limit has been increased from 40 bytes to 70 bytes. A limit is needed because of the word wrapping feature if non-HTML output is specified.

    (Subscription holders: If you'd like this version, ask your sales rep)

    • When recommending a decrease to nproc, make appropriate maxuprc and semmnu recommendations

    • Report on the mapping of legacy & persistent disknames in use on 11.31+ (ctd & diskxx).

    Enhancements to version 7.01.07 (December 14, 2010):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Correctly parse the x/xx/xx date format where xx/xx/xx is expected.
    • Elaborate on how SarCheck detects memory pressure.
    • Tweak the dbc_min_pct recommendation algorithm.
    • Display hostname in the report and the orderform if it's different than sar and uname -n.
    • If legacy & persistent disknames are in use on 11.31+ (ctd & diskxx), only report on ctd names. Build support for mapping the two names in the next release.

    (Subscription holders: If you'd like this version, ask your sales rep)

    • Fix a bug in the parsing of some 11.3x sar reports that caused the system name to be displayed incorrectly in graphs.

    Enhancements to version 7.01.05 (January 29, 2010):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Diagnostic info added to help track down a rare problem calculating the date on a few Itanium 11.3x systems. If your recent copy of SarCheck complains that it's very old or expired, please ask for this version.

    (7.01.04 was never released)

    Enhancements to version 7.01.03 (November 20, 2009):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Change the contact info to show our new address, phone, and fax numbers

    Enhancements to version 7.01.02 (October 5, 2009):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Rewrite inode recommendations because sar's inod-sz field ambiguously stores either the size of the HFS inode cache or the sum of HFS & VXFS inode caches
    • The agent now collects vxfsstat statistics for future analysis
    • Fix cases where SarCheck was using the OS of the system running analyze9000 instead of the OS in the sar report when calculating system table size recommendations

    Enhancements to version 7.01.01 (August 25, 2009):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Stop collecting npar & vpar names. We don't need the information and HP-UX requires root to get this information.

    • Fix a bug in analyze9000 -k, the older way to manage the activation key.
    • Add the date to descriptions of sar errors found in multiday files.
    • Ignore some bad sar -v data that was being graphed.

    Enhancements to version 7.01.00 (June 1, 2009):
    (Subscription holders: If you'd like this version, ask your sales rep)

    • Parse and report on sar -t (tape) data found in 11.3 version of sar
    • Change the default threshold for memory leak detection from 200 to 1000 pgs/hr
    • Reorganize the ps tables when they become full
    • Add PSELFDIR to custom settings
    • Change the default thresholds for swapper CPU utilization to be an indication of memory pressure. Very light CPU usage is not necessarily a sign of memory pressure.

    Enhancements to version 7.00.05 (January 23, 2009):
    (beta version, most fixes are fixes to previous beta versions)

    • Remove dependency on HP-UX to run correctly

    • Get modelno from agent output
    • Add REDCOLOR, PINKCOLOR, and HSIZE chgs to cust settings

    • Tweak nproc recs, 11.3 supports bigger nproc than <11.3
    • Add support for gnuplot 4.2
    • Fix nproc / semmnu when a smaller nproc is recommended
    • Collect getconf MACHINE_SERIAL, vpar name, npar name
    • Add -cs switch to suppress custom settings
    • Add support for parmsfile keywords WIDE
    • Add support for parmsfile keywords PRP PML PLP DBRP DBML DBLP
    • Parms entries to suppress various parameter recs flags = ignore_*
    • On 11.3 vhand will do more so increase vhand_cpu_* thresholds
    • Update usgtext() and helptext() wording.
    • Add agent stuff to ondemand script
    • Look for sar -d stats w/ 'r+w/s' and not 'device' due to 11.3 chgs
    • Allow for unlimited size of open file table in 11.3+
    • Add a table & text of the top cpu using processes
    • Fix some stray text showing up with the -csv switch
    • Fix error from parstatus if not found in analyze -s output

    Enhancements will vary from one platform to another. We have made a conscious decision to avoid using one source tree for different platforms. This way, the version for each platform can evolve according to the needs of the users, and we "cross pollinate" features from one version to another whenever it makes sense.
